| /* 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). | |
