/* 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 drawing all elements of a plot on the canvas. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
Flot normally produces certain elements, like axis labels and the legend, using |
|||
HTML elements. This permits greater interactivity and customization, and often |
|||
looks better, due to cross-browser canvas text inconsistencies and limitations. |
|||
|
|||
It can also be desirable to render the plot entirely in canvas, particularly |
|||
if the goal is to save it as an image, or if Flot is being used in a context |
|||
where the HTML DOM does not exist, as is the case within Node.js. This plugin |
|||
switches out Flot's standard drawing operations for canvas-only replacements. |
|||
|
|||
Currently the plugin supports only axis labels, but it will eventually allow |
|||
every element of the plot to be rendered directly to canvas. |
|||
|
|||
The plugin supports these options: |
|||
|
|||
{ |
|||
canvas: boolean |
|||
} |
|||
|
|||
The "canvas" option controls whether full canvas drawing is enabled, making it |
|||
possible to toggle on and off. This is useful when a plot uses HTML text in the |
|||
browser, but needs to redraw with canvas text when exporting as an image. |

/* Flot plugin for plotting textual data or categories. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
Consider a dataset like [["February", 34], ["March", 20], ...]. This plugin |
|||
allows you to plot such a dataset directly. |
|||
|
|||
To enable it, you must specify mode: "categories" on the axis with the textual |
|||
labels, e.g. |
|||
|
|||
$.plot("#placeholder", data, { xaxis: { mode: "categories" } }); |
|||
|
|||
By default, the labels are ordered as they are met in the data series. If you |
|||
need a different ordering, you can specify "categories" on the axis options |
|||
and list the categories there: |
|||
|
|||
xaxis: { |
|||
mode: "categories", |
|||
categories: ["February", "March", "April"] |
|||
} |
|||
|
|||
If you need to customize the distances between the categories, you can specify |
|||
"categories" as an object mapping labels to values |
|||
|
|||
xaxis: { |
|||
mode: "categories", |
|||
categories: { "February": 1, "March": 3, "April": 4 } |
|||
} |
|||
|
|||
If you don't specify all categories, the remaining categories will be numbered |
|||
from the max value plus 1 (with a spacing of 1 between each). |
|||
|
|||
Internally, the plugin works by transforming the input data through an auto- |
|||
generated mapping where the first category becomes 0, the second 1, etc. |
|||
Hence, a point like ["February", 34] becomes [0, 34] internally in Flot (this |
|||
is visible in hover and click events that return numbers rather than the |
|||
category labels). The plugin also overrides the tick generator to spit out the |
|||
categories as ticks instead of the values. |
|||
|
|||
If you need to map a value back to its label, the mapping is always accessible |
|||
as "categories" on the axis object, e.g. plot.getAxes().xaxis.categories. |

/* Flot plugin for showing crosshairs when the mouse hovers over the plot. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
The plugin supports these options: |
|||
|
|||
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 plotting error bars. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
Error bars are used to show standard deviation and other statistical |
|||
properties in a plot. |
|||
|
|||
* Created by Rui Pereira - rui (dot) pereira (at) gmail (dot) com |
|||
|
|||
This plugin allows you to plot error-bars over points. Set "errorbars" inside |
|||
the points series to the axis name over which there will be error values in |
|||
your data array (*even* if you do not intend to plot them later, by setting |
|||
"show: null" on xerr/yerr). |
|||
|
|||
The plugin supports these options: |
|||
|
|||
series: { |
|||
points: { |
|||
errorbars: "x" or "y" or "xy", |
|||
xerr: { |
|||
show: null/false or true, |
|||
asymmetric: null/false or true, |
|||
upperCap: null or "-" or function, |
|||
lowerCap: null or "-" or function, |
|||
color: null or color, |
|||
radius: null or number |
|||
}, |
|||
yerr: { same options as xerr } |
|||
} |
|||
} |
|||
|
|||
Each data point array is expected to be of the type: |
|||
|
|||
"x" [ x, y, xerr ] |
|||
"y" [ x, y, yerr ] |
|||
"xy" [ x, y, xerr, yerr ] |
|||
|
|||
Where xerr becomes xerr_lower,xerr_upper for the asymmetric error case, and |
|||
equivalently for yerr. Eg., a datapoint for the "xy" case with symmetric |
|||
error-bars on X and asymmetric on Y would be: |
|||
|
|||
[ x, y, xerr, yerr_lower, yerr_upper ] |
|||
|
|||
By default no end caps are drawn. Setting upperCap and/or lowerCap to "-" will |
|||
draw a small cap perpendicular to the error bar. They can also be set to a |
|||
user-defined drawing function, with (ctx, x, y, radius) as parameters, as eg. |
|||
|
|||
function drawSemiCircle( ctx, x, y, radius ) { |
|||
ctx.beginPath(); |
|||
ctx.arc( x, y, radius, 0, Math.PI, false ); |
|||
ctx.moveTo( x - radius, y ); |
|||
ctx.lineTo( x + radius, y ); |
|||
ctx.stroke(); |
|||
} |
|||
|
|||
Color and radius both default to the same ones of the points series if not |
|||
set. The independent radius parameter on xerr/yerr is useful for the case when |
|||
we may want to add error-bars to a line, without showing the interconnecting |
|||
points (with radius: 0), and still showing end caps on the error-bars. |
|||
shadowSize and lineWidth are derived as well from the points series. |

/* Flot plugin for computing bottoms for filled line and bar charts. |

|

Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
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, { lines: { 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. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
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 this: |
|||
|
|||
[ "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. |
|||
|
|||
The plugin supports these options: |
|||
|
|||
series: { |
|||
images: { |
|||
show: boolean |
|||
anchor: "corner" or "center" |
|||
alpha: [ 0, 1 ] |
|||
} |
|||
} |
|||
|
|||
They 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 the ability to pan and zoom the plot. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
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 |
|||
"plotpan" and "plotzoom" events, useful for synchronizing plots. |
|||
|
|||
The plugin supports these 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. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
The plugin assumes that each series has a single data value, and that each |
|||
value is a positive integer or zero. Negative numbers don't make sense for a |
|||
pie chart, and have unpredictable results. The values do NOT need to be |
|||
passed in as percentages; the plugin will calculate the total and per-slice |
|||
percentages internally. |
|||
|
|||
* Created by Brian Medendorp |
|||
|
|||
* Updated with contributions from btburnett3, Anthony Aragues and Xavi Ivars |
|||
|
|||
The plugin supports these options: |
|||
|
|||
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 |
|||
} |
|||
} |

It works by listening for changes on the placeholder div (through the jQuery |
|||
resize event plugin) - if the size changes, it will redraw the plot. |
|||
|
|||
There are no options. If you need to disable the plugin for some plots, you |
|||
can just fix the size of their placeholders. |

/* Flot plugin for selecting regions of a plot. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
The plugin supports these options: |
|||
|
|||
selection: { |
|||
mode: null or "x" or "y" or "xy", |
|||
color: color, |
|||
shape: "round" or "miter" or "bevel", |
|||
minSize: number of pixels |
|||
} |
|||
|
|||
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). "shape" |
|||
is the shape of the corners of the selection. |
|||
|
|||
"minSize" is the minimum size a selection can be in pixels. This value can |
|||
be customized to determine the smallest size a selection can be and still |
|||
have the selection rectangle be displayed. When customizing this value, the |
|||
fact that it refers to pixels, not axis units must be taken into account. |
|||
Thus, for example, if there is a bar graph in time mode with BarWidth set to 1 |
|||
minute, setting "minSize" to 1 will not make the minimum selection size 1 |
|||
minute, but rather 1 pixel. Note also that setting "minSize" to 0 will prevent |
|||
"plotunselected" events from being fired when the user clicks the mouse without |
|||
dragging. |
|||
|
|||
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. As stated above, setting "minSize" to 0 will |
|||
destroy this behavior. |
|||
|
|||
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 rather than overlyaing them. |
|||
|
|||
Copyright (c) 2007-2013 IOLA and Ole Laursen. |
|||
Licensed under the MIT license. |
|||
|
|||
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 the stack option like this: |
|||
|
|||
series: { |
|||
stack: null/false, true, or a key (number/string) |
|||
} |
|||
|
|||
You can also specify it for a single series, like this: |
|||
|
|||
$.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). |

/* Flot plugin for thresholding data. |

The plugin supports these options: |
|||
|
|||
series: { |
|||
threshold: { |
|||
below: number |
|||
color: colorspec |
|||
} |
|||
} |
|||
|
|||
It can also be applied to a single series, like this: |
|||
|
|||
$.plot( $("#placeholder"), [{ |
|||
data: [ ... ], |
|||
threshold: { ... } |
|||
}]) |
|||
|
|||
An array can be passed for multiple thresholding, like this: |
|||
|
|||
threshold: [{ |
|||
below: number1 |
|||
color: color1 |
|||
},{ |
|||
below: number2 |
|||
color: color2 |
|||
}] |
|||
|
|||
These multiple threshold objects can be passed in any order since they are |
|||
sorted by the processing function. |
|||
|
|||
The data points below "below" are drawn with the specified color. This makes |
|||
it easy to mark points below 0, e.g. for budget data. |
|||
|
|||
Internally, the plugin works by splitting the data into two series, above and |
|||
below the threshold. The extra series below the threshold will have its label |
|||
cleared and the special "originSeries" attribute set to the original series. |
|||
You may need to check for this in hover events. |
