-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).

-/* 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 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).
