+/* Plugin for jQuery for working with colors.
+ *
+ * Version 1.1.
+ *
+ * Inspiration from jQuery color animation plugin by John Resig.
+ *
+ * Released under the MIT license by Ole Laursen, October 2009.
+ *
+ * Examples:
+ *
+ * $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
+ * var c = $.color.extract($("#mydiv"), 'background-color');
+ * console.log(c.r, c.g, c.b, c.a);
+ * $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
+ *
+ * Note that .scale() and .add() return the same modified object
+ * instead of making a new one.
+ *
+ * V. 1.1: Fix error handling so e.g. parsing an empty string does
+ * produce a color rather than just crashing.

+Flot plugin for showing crosshairs, 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" is in coordinates of the plot and
+ should be on the form { x: xpos, y: ypos } (you can use x2/x3/...
+ if you're using multiple 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 computing bottoms for filled line and bar charts.
+The case: you've got two series that you want to fill the area
+between. In Flot terms, you need to use one as the fill bottom of the
+other. You can specify the bottom of each data point as the third
+coordinate manually, or you can use this plugin to compute it for you.
+
+In order to name the other series, you need to give it an id, like this
+
+ var dataset = [
+ { data: [ ... ], id: "foo" } , // use default bottom
+ { data: [ ... ], fillBetween: "foo" }, // use first dataset as bottom
+ ];
+
+ $.plot($("#placeholder"), dataset, { line: { show: true, fill: true }});
+
+As a convenience, if the id given is a number that doesn't appear as
+an id in the series, it is interpreted as the index in the array
+instead (so fillBetween: 0 can also mean the first series).
+
+Internally, the plugin modifies the datapoints in each series. For
+line series, extra data points might be inserted through
+interpolation. Note that at points where the bottom line is not
+defined (due to a null point or start/end of line), the current line
+will show a gap too. The algorithm comes from the jquery.flot.stack.js
+plugin, possibly some code could be shared.

+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.
+
+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
+ cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer"
+ frameRate: 20
+ }
+
+ xaxis, yaxis, x2axis, y2axis: {
+ zoomRange: null // or [number, number] (min range, max range) or false
+ panRange: null // or [number, number] (min, max) or false
+ }
+
+"interactive" enables the built-in drag/click behaviour. If you enable
+interactive for pan, then you'll have a basic plot that supports
+moving around; the same for zoom.
+
+"amount" specifies the default amount to zoom in (so 1.5 = 150%)
+relative to the current viewport.
+
+"cursor" is a standard CSS mouse cursor string used for visual
+feedback to the user when dragging.
+
+"frameRate" specifies the maximum number of times per second the plot
+will update itself while the user is panning around on it (set to null
+to disable intermediate pans, the plot will then not update until the
+mouse button is released).
+
+"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 end to null to ignore, e.g. [1, null]. If you set
+zoomRange to false, zooming on that axis will be disabled.
+
+"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, e.g. [-10, null]. If you set
+panRange to false, panning on that axis will be disabled.
+
+Example API usage:
+
+ plot = $.plot(...);
+
+ // zoom default amount in on the pixel (10, 20)
+ plot.zoom({ center: { left: 10, top: 20 } });
+
+ // zoom out again
+ plot.zoomOut({ center: { left: 10, top: 20 } });
+
+ // zoom 200% in on the pixel (10, 20)
+ plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
+
+ // pan 100 pixels to the left and 20 down
+ plot.pan({ left: -100, top: 20 })
+
+Here, "center" specifies where the center of the zooming should
+happen. Note that this is defined in pixel space, not the space of the
+data points (you can use the p2c helpers on the axes in Flot to help
+you convert between these).
+
+"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). You can set the default in the options.

+Flot plugin for rendering pie charts. The plugin assumes the data is
+coming is as a single data value for each series, and each of those
+values is a positive value or zero (negative numbers don't make
+any sense and will cause strange effects). The data values do
+NOT need to be passed in as percentage values because it
+internally calculates the total and percentages.
+
+* Created by Brian Medendorp, June 2009
+* Updated November 2009 with contributions from: btburnett3, Anthony Aragues and Xavi Ivars
+
+* Changes:
+ 2009-10-22: lineJoin set to round
+ 2009-10-23: IE full circle fix, donut
+ 2009-11-11: Added basic hover from btburnett3 - does not work in IE, and center is off in Chrome and Opera
+ 2009-11-17: Added IE hover capability submitted by Anthony Aragues
+ 2009-11-18: Added bug fix submitted by Xavi Ivars (issues with arrays when other JS libraries are included as well)
+
+
+Available options are:
+series: {
+ pie: {
+ show: true/false
+ radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
+ innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
+ startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
+ tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
+ offset: {
+ top: integer value to move the pie up or down
+ left: integer value to move the pie left or right, or 'auto'
+ },
+ stroke: {
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
+ width: integer pixel width of the stroke
+ },
+ label: {
+ show: true/false, or 'auto'
+ formatter: a user-defined function that modifies the text/style of the label text
+ radius: 0-1 for percentage of fullsize, or a specified pixel length
+ background: {
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
+ opacity: 0-1
+ },
+ threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
+ },
+ combine: {
+ threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
+ label: any text value of what the combined slice should be labeled
+ }
+ highlight: {
+ opacity: 0-1
+ }
+ }
+}
+
+More detail and specific examples can be found in the included HTML file.

+Flot plugin for selecting regions.
+
+The plugin defines the following options:
+
+ selection: {
+ mode: null or "x" or "y" or "xy",
+ color: color
+ }
+
+Selection support is enabled 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
+(if you need to change the color later on, you can get to it with
+plot.getOptions().selection.color).
+
+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 a 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 - with multiple axes, the extra ones are in
+ // x2axis, x3axis, ...
+ });
+
+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 range, if the mode is "y"
+ you need to put in an yaxis range and both xaxis and yaxis 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. If you
+ are using multiple axes, you can specify the ranges on any of those,
+ e.g. as x2axis/x3axis/... instead of xaxis, the plugin picks the
+ first one it sees.
+
+- 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.

+Flot plugin for stacking data sets, i.e. putting them on top of each
+other, for accumulative graphs.
+The plugin assumes the data is sorted on x (or y if stacking
+horizontally). For line charts, it is assumed that if a line has an
+undefined gap (from a null point), then the line above it should have
+the same gap - insert zeros instead of "null" if you want another
+behaviour. This also holds for the start and end of the chart. 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. If there's a second y value, it's also
+adjusted (e.g for bar charts or filled areas).
