+Frequently asked questions
+--------------------------
+
+Q: How much data can Flot cope with?
+
+A: Flot will happily draw everything you send to it so the answer
+depends on the browser. The excanvas emulation used for IE (built with
+VML) makes IE by far the slowest browser so be sure to test with that
+if IE users are in your target group.
+
+1000 points is not a problem, but as soon as you start having more
+points than the pixel width, you should probably start thinking about
+downsampling/aggregation as this is near the resolution limit of the
+chart anyway. If you downsample server-side, you also save bandwidth.
+
+
+Q: Flot isn't working when I'm using JSON data as source!
+
+A: Actually, Flot loves JSON data, you just got the format wrong.
+Double check that you're not inputting strings instead of numbers,
+like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and
+the error might not show up immediately because Javascript can do some
+conversion automatically.
+
+
+Q: Can I export the graph?
+
+A: This is a limitation of the canvas technology. There's a hook in
+the canvas object for getting an image out, but you won't get the tick
+labels. And it's not likely to be supported by IE. At this point, your
+best bet is probably taking a screenshot, e.g. with PrtScn.
+
+
+Q: The bars are all tiny in time mode?
+
+A: It's not really possible to determine the bar width automatically.
+So you have to set the width with the barWidth option which is NOT in
+pixels, but in the units of the x axis (or the y axis for horizontal
+bars). For time mode that's milliseconds so the default value of 1
+makes the bars 1 millisecond wide.
+
+
+Q: Can I use Flot with libraries like Mootools or Prototype?
+
+A: Yes, Flot supports it out of the box and it's easy! Just use jQuery
+instead of $, e.g. call jQuery.plot instead of $.plot and use
+jQuery(something) instead of $(something). As a convenience, you can
+put in a DOM element for the graph placeholder where the examples and
+the API documentation are using jQuery objects.
+
+Depending on how you include jQuery, you may have to add one line of
+code to prevent jQuery from overwriting functions from the other
+libraries, see the documentation in jQuery ("Using jQuery with other
+libraries") for details.
+
+
+Q: Flot doesn't work with [widget framework xyz]!
+
+A: The problem is most likely within the framework, or your use of the
+framework.
+
+The only non-standard thing used by Flot is the canvas tag; otherwise
+it is simply a series of absolute positioned divs within the
+placeholder tag you put in. If this is not working, it's probably
+because the framework you're using is doing something weird with the
+DOM. As a last resort, you might try replotting and see if it helps.
+
+If you find there's a specific thing we can do to Flot to help, feel
+free to submit a bug report. Otherwise, you're welcome to ask for help
+on the mailing list, but please don't submit a bug report to Flot -
+try the framework instead.

+Flot 0.6
+--------
+
+API changes:
+
+1. Selection support has been moved to a plugin. Thus if you're
+passing selection: { mode: something }, you MUST include the file
+jquery.flot.selection.js after jquery.flot.js. This reduces the size
+of base Flot and makes it easier to customize the selection as well as
+improving code clarity. The change is based on patch from andershol.
+
+2. In the global options specified in the $.plot command,
+"lines", "points", "bars" and "shadowSize" have been moved to a
+sub-object called "series", i.e.
+
+  $.plot(placeholder, data, { lines: { show: true }})
+
+should be changed to
+
+  $.plot(placeholder, data, { series: { lines: { show: true }}})
+
+All future series-specific options will go into this sub-object to
+simplify plugin writing. Backward-compatibility code is in place, so
+old code should not break.
+
+3. "plothover" no longer provides the original data point, but instead
+a normalized one, since there may be no corresponding original point.
+
+4. Due to a bug in previous versions of jQuery, you now need at least
+jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
+improvements in event handling speed.
+
+
+Changes:
+
+- Added support for disabling interactivity for specific data series
+  (request from Ronald Schouten and Steve Upton).
+
+- Flot now calls $() on the placeholder and optional legend container
+  passed in so you can specify DOM elements or CSS expressions to make
+  it easier to use Flot with libraries like Prototype or Mootools or
+  through raw JSON from Ajax responses.
+
+- A new "plotselecting" event is now emitted while the user is making
+  a selection.
+
+- The "plothover" event is now emitted immediately instead of at most
+  10 times per second, you'll have to put in a setTimeout yourself if
+  you're doing something really expensive on this event.
+
+- The built-in date formatter can now be accessed as
+  $.plot.formatDate(...) (suggestion by Matt Manela) and even
+  replaced.
+
+- Added "borderColor" option to the grid (patch from Amaury Chamayou
+  and patch from Mike R. Williamson).
+
+- Added support for gradient backgrounds for the grid, take a look at
+  the "setting options" example (based on patch from Amaury Chamayou,
+  issue 90).
+
+- Gradient bars (suggestion by stefpet).
+  
+- Added a "plotunselected" event which is triggered when the selection
+  is removed, see "selection" example (suggestion by Meda Ugo);
+
+- The option legend.margin can now specify horizontal and vertical
+  margins independently (suggestion by someone who's annoyed).
+
+- Data passed into Flot is now copied to a new canonical format to
+  enable further processing before it hits the drawing routines. As a
+  side-effect, this should make Flot more robust in the face of bad
+  data (and fixes issue 112).
+
+- Step-wise charting: line charts have a new option "steps" that when
+  set to true connects the points with horizontal/vertical steps
+  instead of diagonal lines.
+
+- The legend labelFormatter now passes the series in addition to just
+  the label (suggestion by Vincent Lemeltier).
+
+- Horizontal bars (based on patch by Jason LeBrun).
+
+- Support for partial bars by specifying a third coordinate, i.e. they
+  don't have to start from the axis. This can be used to make stacked
+  bars.
+
+- New option to disable the (grid.show).
+
+- Added pointOffset method for converting a point in data space to an
+  offset within the placeholder.
+  
+- Plugin system: register an init method in the $.flot.plugins array
+  to get started, see PLUGINS.txt for details on how to write plugins
+  (it's easy). There are also some extra methods to enable access to
+  internal state.
+
+- Hooks: you can register functions that are called while Flot is
+  crunching the data and doing the plot. This can be used to modify
+  Flot without changing the source, useful for writing plugins. Some
+  hooks are defined, more are likely to come.
+  
+- Threshold plugin: you can set a threshold and a color, and the data
+  points below that threshold will then get the color. Useful for
+  marking data below 0, for instance.
+
+- Stack plugin: you can specify a stack key for each series to have
+  them summed. This is useful for drawing additive/cumulative graphs
+  with bars and (currently unfilled) lines.
+
+- Crosshairs plugin: trace the mouse position on the axes, enable with
+  crosshair: { mode: "x"} (see the new tracking example for a use).
+
+- Image plugin: plot prerendered images.
+
+- Navigation plugin for panning and zooming a plot.
+
+- More configurable grid.
+
+- Axis transformation support, useful for non-linear plots, e.g. log
+  axes and compressed time axes (like omitting weekends).
+
+- Support for twelve-hour date formatting (patch by Forrest Aldridge).
+
+- The color parsing code in Flot has been cleaned up and split out so
+  it's now available as a separate jQuery plugin. It's included inline
+  in the Flot source to make dependency managing easier. This also
+  makes it really easy to use the color helpers in Flot plugins.
+
+Bug fixes:
+
+- Fixed two corner-case bugs when drawing filled curves (report and
+  analysis by Joshua Varner).
+- Fix auto-adjustment code when setting min to 0 for an axis where the
+  dataset is completely flat on that axis (report by chovy).
+- Fixed a bug with passing in data from getData to setData when the
+  secondary axes are used (issue 65, reported by nperelman).
+- Fixed so that it is possible to turn lines off when no other chart
+  type is shown (based on problem reported by Glenn Vanderburg), and
+  fixed so that setting lineWidth to 0 also hides the shadow (based on
+  problem reported by Sergio Nunes).
+- Updated mousemove position expression to the latest from jQuery (bug
+  reported by meyuchas).
+- Use CSS borders instead of background in legend (fix printing issue 25
+  and 45).
+- Explicitly convert axis min/max to numbers.
+- Fixed a bug with drawing marking lines with different colors
+  (reported by Khurram).
+- Fixed a bug with returning y2 values in the selection event (fix
+  by exists, issue 75).
+- Only set position relative on placeholder if it hasn't already a
+  position different from static (reported by kyberneticist, issue 95).
+- Don't round markings to prevent sub-pixel problems (reported by Dan
+  Lipsitt).
+- Make the grid border act similarly to a regular CSS border, i.e.
+  prevent it from overlapping the plot itself. This also fixes a
+  problem with anti-aliasing when the width is 1 pixel (reported by
+  Anthony Ettinger).
+- Imported version 3 of excanvas and fixed two issues with the newer
+  version. Hopefully, this will make Flot work with IE8 (nudge by
+  Fabien Menager, further analysis by Booink, issue 133).
+- Changed the shadow code for lines to hopefully look a bit better
+  with vertical lines.
+- Round tick positions to avoid possible problems with fractions
+  (suggestion by Fred, issue 130).
+- Made the heuristic for determining how many ticks to aim for a bit
+  smarter.
+- Fix for uneven axis margins (report and patch by Paul Kienzle) and
+  snapping to ticks (concurrent report and patch by lifthrasiir).
+- Fixed bug with slicing in findNearbyItems (patch by zollman).
+- Make heuristic for x axis label widths more dynamic (patch by
+  rickinhethuis).
+- Make sure points on top take precedence when finding nearby points
+  when hovering (reported by didroe, issue 224).
+
+Flot 0.5
+--------
+
+Backwards API change summary: Timestamps are now in UTC. Also
+"selected" event -> becomes "plotselected" with new data, the
+parameters for setSelection are now different (but backwards
+compatibility hooks are in place), coloredAreas becomes markings with
+a new interface (but backwards compatibility hooks are in place).
+
+
+Interactivity: added a new "plothover" event and this and the
+"plotclick" event now returns the closest data item (based on patch by
+/david, patch by Mark Byers for bar support). See the revamped
+"interacting with the data" example for some hints on what you can do.
+
+Highlighting: you can now highlight points and datapoints are
+autohighlighted when you hover over them (if hovering is turned on).
+
+Support for dual axis has been added (based on patch by someone who's
+annoyed and /david). For each data series you can specify which axes
+it belongs to, and there are two more axes, x2axis and y2axis, to
+customize. This affects the "selected" event which has been renamed to
+"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
+setSelection in which the parameters are on a new form (backwards
+compatible hooks are in place so old code shouldn't break) and
+markings (formerly coloredAreas).
+
+Timestamps in time mode are now displayed according to
+UTC instead of the time zone of the visitor. This affects the way the
+timestamps should be input; you'll probably have to offset the
+timestamps according to your local time zone. It also affects any
+custom date handling code (which basically now should use the
+equivalent UTC date mehods, e.g. .setUTCMonth() instead of
+.setMonth().
+
+Added support for specifying the size of tick labels (axis.labelWidth,
+axis.labelHeight). Useful for specifying a max label size to keep
+multiple plots aligned.
+
+Markings, previously coloredAreas, are now specified as ranges on the
+axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
+you can now draw horizontal/vertical lines by setting from and to to
+the same coordinate (idea from line support patch by by Ryan Funduk).
+
+The "fill" option can now be a number that specifies the opacity of
+the fill.
+
+You can now specify a coordinate as null (like [2, null]) and Flot
+will take the other coordinate into account when scaling the axes
+(based on patch by joebno).
+
+New option for bars "align". Set it to "center" to center the bars on
+the value they represent.
+
+setSelection now takes a second parameter which you can use to prevent
+the method from firing the "plotselected" handler. 
+
+Using the "container" option in legend now overwrites the container
+element instead of just appending to it (fixes infinite legend bug,
+reported by several people, fix by Brad Dewey).
+
+Fixed a bug in calculating spacing around the plot (reported by
+timothytoe). Fixed a bug in finding max values for all-negative data
+sets. Prevent the possibility of eternal looping in tick calculations.
+Fixed a bug when borderWidth is set to 0 (reported by
+Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
+(reported by James Hewitt, patch by Ryan Funduk). Fixed a
+bug with line widths of bars (reported by MikeM). Fixed a bug with
+'nw' and 'sw' legend positions. Improved the handling of axis
+auto-scaling with bars. Fixed a bug with multi-line x-axis tick
+labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
+
+
+Flot 0.4
+--------
+
+API changes: deprecated axis.noTicks in favor of just specifying the
+number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
+"xaxis: { ticks: 10 }"
+
+Time series support. Specify axis.mode: "time", put in Javascript
+timestamps as data, and Flot will automatically spit out sensible
+ticks. Take a look at the two new examples. The format can be
+customized with axis.timeformat and axis.monthNames, or if that fails
+with axis.tickFormatter.
+
+Support for colored background areas via grid.coloredAreas. Specify an
+array of { x1, y1, x2, y2 } objects or a function that returns these
+given { xmin, xmax, ymin, ymax }.
+
+More members on the plot object (report by Chris Davies and others).
+"getData" for inspecting the assigned settings on data series (e.g.
+color) and "setData", "setupGrid" and "draw" for updating the contents
+without a total replot.
+
+The default number of ticks to aim for is now dependent on the size of
+the plot in pixels. Support for customizing tick interval sizes
+directly with axis.minTickSize and axis.tickSize.
+
+Cleaned up the automatic axis scaling algorithm and fixed how it
+interacts with ticks. Also fixed a couple of tick-related corner case
+bugs (one reported by mainstreetmark, another reported by timothytoe).
+
+The option axis.tickFormatter now takes a function with two
+parameters, the second parameter is an optional object with
+information about the axis. It has min, max, tickDecimals, tickSize.
+
+Added support for segmented lines (based on patch from Michael
+MacDonald) and for ignoring null and bad values (suggestion from Nick
+Konidaris and joshwaihi). 
+
+Added support for changing the border width (joebno and safoo).
+Label colors can be changed via CSS by selecting the tickLabel class.
+
+Fixed a bug in handling single-item bar series (reported by Emil
+Filipov). Fixed erratic behaviour when interacting with the plot
+with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
+selection when selecting stuff on the canvas.
+
+
+
+Flot 0.3
+--------
+
+This is mostly a quick-fix release because jquery.js wasn't included
+in the previous zip/tarball.
+
+Support clicking on the plot. Turn it on with grid: { clickable: true },
+then you get a "plotclick" event on the graph placeholder with the
+position in units of the plot.
+
+Fixed a bug in dealing with data where min = max, thanks to Michael
+Messinides.
+
+Include jquery.js in the zip/tarball.
+
+
+Flot 0.2
+--------
+
+Added support for putting a background behind the default legend. The
+default is the partly transparent background color. Added
+backgroundColor and backgroundOpacity to the legend options to control
+this.
+
+The ticks options can now be a callback function that takes one
+parameter, an object with the attributes min and max. The function
+should return a ticks array.
+
+Added labelFormatter option in legend, useful for turning the legend
+labels into links.
+
+Fixed a couple of bugs.
+
+The API should now be fully documented.
+
+Patch from Guy Fraser to make parts of the code smaller.
+
+API changes: Moved labelMargin option to grid from x/yaxis.
+
+
+Flot 0.1
+--------
+
+First public release.

+Writing plugins
+---------------
+
+To make a new plugin, create an init function and a set of options (if
+needed), stuff it into an object and put it in the $.plot.plugins
+array. For example:
+
+  function myCoolPluginInit(plot) { plot.coolstring = "Hello!" };
+  var myCoolOptions = { coolstuff: { show: true } }
+  $.plot.plugins.push({ init: myCoolPluginInit, options: myCoolOptions });
+
+  // now when $.plot is called, the returned object will have the
+  // attribute "coolstring"
+
+Now, given that the plugin might run in many different places, it's
+a good idea to avoid leaking names. We can avoid this by wrapping the
+above lines in an anonymous function which we call immediately, like
+this: (function () { inner code ... })(). To make it even more robust
+in case $ is not bound to jQuery but some other Javascript library, we
+can write it as
+
+  (function ($) {
+    // plugin definition
+    // ...
+  })(jQuery);
+
+Here is a simple debug plugin which alerts each of the series in the
+plot. It has a single option that control whether it is enabled and
+how much info to output:
+
+  (function ($) {
+    function init(plot) {
+      var debugLevel = 1;
+    
+      function checkDebugEnabled(plot, options) {
+        if (options.debug) {
+          debugLevel = options.debug;
+            
+          plot.hooks.processDatapoints.push(alertSeries);
+        }
+      }
+
+      function alertSeries(plot, series, datapoints) {
+        var msg = "series " + series.label;
+        if (debugLevel > 1)
+          msg += " with " + series.data.length + " points";
+        alert(msg);
+      }
+    
+      plot.hooks.processOptions.push(checkDebugEnabled);
+    }
+
+    var options = { debug: 0 };
+    
+    $.plot.plugins.push({
+        init: init,
+        options: options,
+        name: "simpledebug",
+        version: "0.1"
+    });
+  })(jQuery);
+
+We also define "name" and "version". It's not used by Flot, but might
+be helpful for other plugins in resolving dependencies.
+  
+Put the above in a file named "jquery.flot.debug.js", include it in an
+HTML page and then it can be used with:
+
+  $.plot($("#placeholder"), [...], { debug: 2 });
+
+This simple plugin illustrates a couple of points:
+
+ - It uses the anonymous function trick to avoid name pollution.
+ - It can be enabled/disabled through an option.
+ - Variables in the init function can be used to store plot-specific
+   state between the hooks.
+
+ 
+Options guidelines
+==================
+   
+Plugins should always support appropriate options to enable/disable
+them because the plugin user may have several plots on the same page
+where only one should use the plugin.
+
+If the plugin needs series-specific options, you can put them in
+"series" in the options object, e.g.
+
+  var options = {
+    series: {
+      downsample: {
+        algorithm: null,
+        maxpoints: 1000
+      }
+    }
+  }
+
+Then they will be copied by Flot into each series, providing the
+defaults in case the plugin user doesn't specify any. Again, in most
+cases it's probably a good idea if the plugin is turned off rather
+than on per default, just like most of the powerful features in Flot.
+
+Think hard and long about naming the options. These names are going to
+be public API, and code is going to depend on them if the plugin is
+successful.

+About
+-----
+
+Flot is a Javascript plotting library for jQuery. Read more at the
+website:
+
+  http://code.google.com/p/flot/
+
+Take a look at the examples linked from above, they should give a good
+impression of what Flot can do and the source code of the examples is
+probably the fastest way to learn how to use Flot.
+  
+
+Installation
+------------
+
+Just include the Javascript file after you've included jQuery.
+
+Note that you need to get a version of Excanvas (e.g. the one bundled
+with Flot) which is canvas emulation on Internet Explorer. You can
+include the excanvas script like this:
+
+  <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.pack.js"></script><![endif]-->
+
+If it's not working on your development IE 6.0, check that it has
+support for VML which excanvas is relying on. It appears that some
+stripped down versions used for test environments on virtual machines
+lack the VML support.
+  
+Also note that you need at least jQuery 1.2.6 (but at least jQuery
+1.3.2 is recommended for interactive charts because of performance
+improvements in event handling).
+
+
+Basic usage
+-----------
+
+Create a placeholder div to put the graph in:
+
+   <div id="placeholder"></div>
+
+You need to set the width and height of this div, otherwise the plot
+library doesn't know how to scale the graph. You can do it inline like
+this:
+
+   <div id="placeholder" style="width:600px;height:300px"></div>
+
+You can also do it with an external stylesheet. Make sure that the
+placeholder isn't within something with a display:none CSS property -
+in that case, Flot has trouble measuring label dimensions which
+results in garbled looks and might have trouble measuring the
+placeholder dimensions which is fatal (it'll throw an exception).
+
+Then when the div is ready in the DOM, which is usually on document
+ready, run the plot function:
+
+  $.plot($("#placeholder"), data, options);
+
+Here, data is an array of data series and options is an object with
+settings if you want to customize the plot. Take a look at the
+examples for some ideas of what to put in or look at the reference
+in the file "API.txt". Here's a quick example that'll draw a line from
+(0, 0) to (1, 1):
+
+  $.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
+
+The plot function immediately draws the chart and then returns a plot
+object with a couple of methods.
+
+
+What's with the name?
+---------------------
+
+First: it's pronounced with a short o, like "plot". Not like "flawed".
+
+So "Flot" rhymes with "plot".
+
+And if you look up "flot" in a Danish-to-English dictionary, some up
+the words that come up are "good-looking", "attractive", "stylish",
+"smart", "impressive", "extravagant". One of the main goals with Flot
+is pretty looks.

+
+    <p>Example of loading data dynamically with AJAX. Percentage change in GDP (source: <a href="http://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=en&pcode=tsieb020">Eurostat</a>). Click the buttons below.</p>
+
+    <p>The data is fetched over HTTP, in this case directly from text
+    files. Usually the URL would point to some web server handler
+    (e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that
+    extracts it from a database and serializes it to JSON.</p>
+
+    <p>
+      <input class="fetchSeries" type="button" value="First dataset"> -
+      <a href="data-eu-gdp-growth.json">data</a> -
+      <span></span>
+    </p>
+
+    <p>
+      <input class="fetchSeries" type="button" value="Second dataset"> -

+    <p>With the image plugin, you can plot images. This is for example
+    useful for getting ticks on complex prerendered visualizations.
+    Instead of inputting data points, you put in the images and where
+    their two opposite corners are supposed to be in plot space.</p>
+
+    <p>Images represent a little further complication because you need
+    to make sure they are loaded before you can use them (Flot skips
+    incomplete images). The plugin comes with a couple of helpers

+
+    <p>The idea is that Flot goes to great lengths to provide <b>sensible
+    defaults</b> which you can then customize as needed for your
+    particular application. If you've found a use case where the
+    defaults can be improved, please don't hesitate to give your

+ *   var c = $.color.extract($("#mydiv"), 'background-color');

+Flot plugin for showing a crosshair, thin lines, when the mouse hovers
+over the plot.
+
+  crosshair: {
+    mode: null or "x" or "y" or "xy"
+    color: color
+    lineWidth: number
+  }
+
+Set the mode to one of "x", "y" or "xy". The "x" mode enables a
+vertical crosshair that lets you trace the values on the x axis, "y"
+enables a horizontal crosshair and "xy" enables them both. "color" is
+the color of the crosshair (default is "rgba(170, 0, 0, 0.80)"),
+"lineWidth" is the width of the drawn lines (default is 1).
+
+The plugin also adds four public methods:
+
+  - setCrosshair(pos)
+
+    Set the position of the crosshair. Note that this is cleared if
+    the user moves the mouse. "pos" should be on the form { x: xpos,
+    y: ypos } (or x2 and y2 if you're using the secondary axes), which
+    is coincidentally the same format as what you get from a "plothover"
+    event. If "pos" is null, the crosshair is cleared.
+
+  - clearCrosshair()
+
+    Clear the crosshair.
+
+  - lockCrosshair(pos)
+
+    Cause the crosshair to lock to the current location, no longer
+    updating if the user moves the mouse. Optionally supply a position
+    (passed on to setCrosshair()) to move it to.
+
+    Example usage:
+      var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
+      $("#graph").bind("plothover", function (evt, position, item) {
+        if (item) {
+          // Lock the crosshair to the data point being hovered
+          myFlot.lockCrosshair({ x: item.datapoint[0], y: item.datapoint[1] });
+        }
+        else {
+          // Return normal crosshair operation
+          myFlot.unlockCrosshair();
+        }
+      });
+
+  - unlockCrosshair()
+
+    Free the crosshair to move again after locking it.

+Flot plugin for plotting images, e.g. useful for putting ticks on a
+prerendered complex visualization.
+
+The data syntax is [[image, x1, y1, x2, y2], ...] where (x1, y1) and
+(x2, y2) are where you intend the two opposite corners of the image to
+end up in the plot. Image must be a fully loaded Javascript image (you
+can make one with new Image()). If the image is not complete, it's
+skipped when plotting.
+
+There are two helpers included for retrieving images. The easiest work
+the way that you put in URLs instead of images in the data (like
+["myimage.png", 0, 0, 10, 10]), then call $.plot.image.loadData(data,
+options, callback) where data and options are the same as you pass in
+to $.plot. This loads the images, replaces the URLs in the data with
+the corresponding images and calls "callback" when all images are
+loaded (or failed loading). In the callback, you can then call $.plot
+with the data set. See the included example.
+
+A more low-level helper, $.plot.image.load(urls, callback) is also
+included. Given a list of URLs, it calls callback with an object
+mapping from URL to Image object when all images are loaded or have
+failed loading.
+
+Options for the plugin are
+
+  series: {
+      images: {
+          show: boolean
+          anchor: "corner" or "center"
+          alpha: [0,1]
+      }
+  }
+
+which can be specified for a specific series
+
+  $.plot($("#placeholder"), [{ data: [ ... ], images: { ... } ])
+
+Note that because the data format is different from usual data points,
+you can't use images with anything else in a specific data series.
+
+Setting "anchor" to "center" causes the pixels in the image to be
+anchored at the corner pixel centers inside of at the pixel corners,
+effectively letting half a pixel stick out to each side in the plot.
+
+
+A possible future direction could be support for tiling for large
+images (like Google Maps).

+Flot plugin for adding panning and zooming capabilities to a plot.
+
+The default behaviour is double click and scrollwheel up/down to zoom
+in, drag to pan. The plugin defines plot.zoom({ center }),
+plot.zoomOut() and plot.pan(offset) so you easily can add custom
+controls. It also fires a "plotpan" and "plotzoom" event when
+something happens, useful for synchronizing plots.
+
+Example usage:
+
+  plot = $.plot(...);
+  
+  // zoom default amount in on the pixel (100, 200) 
+  plot.zoom({ center: { left: 10, top: 20 } });
+
+  // zoom out again
+  plot.zoomOut({ center: { left: 10, top: 20 } });
+
+  // pan 100 pixels to the left and 20 down
+  plot.pan({ left: -100, top: 20 })
+
+
+Options:
+
+  zoom: {
+    interactive: false
+    trigger: "dblclick" // or "click" for single click
+    amount: 1.5         // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
+  }
+  
+  pan: {
+    interactive: false
+  }
+
+  xaxis, yaxis, x2axis, y2axis: {
+    zoomRange: null  // or [number, number] (min range, max range)
+    panRange: null   // or [number, number] (min, max)
+  }
+  
+"interactive" enables the built-in drag/click behaviour. "amount" is
+the amount to zoom the viewport relative to the current range, so 1 is
+100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is 70% (zoom out).
+
+"zoomRange" is the interval in which zooming can happen, e.g. with
+zoomRange: [1, 100] the zoom will never scale the axis so that the
+difference between min and max is smaller than 1 or larger than 100.
+You can set either of them to null to ignore.
+
+"panRange" confines the panning to stay within a range, e.g. with
+panRange: [-10, 20] panning stops at -10 in one end and at 20 in the
+other. Either can be null.

+Flot plugin for selecting regions.
+
+The plugin defines the following options:
+
+  selection: {
+    mode: null or "x" or "y" or "xy",
+    color: color
+  }
+
+You enable selection support by setting the mode to one of "x", "y" or
+"xy". In "x" mode, the user will only be able to specify the x range,
+similarly for "y" mode. For "xy", the selection becomes a rectangle
+where both ranges can be specified. "color" is color of the selection.
+
+When selection support is enabled, a "plotselected" event will be emitted
+on the DOM element you passed into the plot function. The event
+handler gets one extra parameter with the ranges selected on the axes,
+like this:
+
+  placeholder.bind("plotselected", function(event, ranges) {
+    alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
+    // similar for yaxis, secondary axes are in x2axis
+    // and y2axis if present
+  });
+
+The "plotselected" event is only fired when the user has finished
+making the selection. A "plotselecting" event is fired during the
+process with the same parameters as the "plotselected" event, in case
+you want to know what's happening while it's happening,
+
+A "plotunselected" event with no arguments is emitted when the user
+clicks the mouse to remove the selection.
+
+The plugin allso adds the following methods to the plot object:
+
+- setSelection(ranges, preventEvent)
+
+  Set the selection rectangle. The passed in ranges is on the same
+  form as returned in the "plotselected" event. If the selection
+  mode is "x", you should put in either an xaxis (or x2axis) object,
+  if the mode is "y" you need to put in an yaxis (or y2axis) object
+  and both xaxis/x2axis and yaxis/y2axis if the selection mode is
+  "xy", like this:
+
+    setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
+
+  setSelection will trigger the "plotselected" event when called. If
+  you don't want that to happen, e.g. if you're inside a
+  "plotselected" handler, pass true as the second parameter.
+  
+- clearSelection(preventEvent)
+
+  Clear the selection rectangle. Pass in true to avoid getting a
+  "plotunselected" event.
+
+- getSelection()
+
+  Returns the current selection in the same format as the
+  "plotselected" event. If there's currently no selection, the
+  function returns null.
+

+

+    function init(plot) {
+        var selection = {
+                first: { x: -1, y: -1}, second: { x: -1, y: -1},
+                show: false,
+                active: false
+            };
+
+        // FIXME: The drag handling implemented here should be
+        // abstracted out, there's some similar code from a library in
+        // the navigation plugin, this should be massaged a bit to fit

+        // make this plugin much slimmer.

+/*
+Flot plugin for stacking data sets, i.e. putting them on top of each
+other, for accumulative graphs. Note that the plugin assumes the data
+is sorted on x. Also note that stacking a mix of positive and negative
+values in most instances doesn't make sense (so it looks weird).
+
+Two or more series are stacked when their "stack" attribute is set to
+the same key (which can be any number or string or just "true"). To
+specify the default stack, you can set
+
+  series: {
+    stack: null or true or key (number/string)
+  }
+
+or specify it for a specific series
+
+  $.plot($("#placeholder"), [{ data: [ ... ], stack: true ])
+  
+The stacking order is determined by the order of the data series in
+the array (later series end up on top of the previous).
+
+Internally, the plugin modifies the datapoints in each series, adding
+an offset to the y value. For line series, extra data points are
+inserted through interpolation. For bar charts, the second y value is
+also adjusted.
