/* Flot plugin for plotting textual data or categories.
|
||||
|
||||
Copyright (c) 2007-2014 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 rendering pie charts.
|
||||
|
||||
Copyright (c) 2007-2014 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
|
||||
}
|

/* Flot plugin for automatically redrawing plots as the placeholder resizes.

|
||||
Copyright (c) 2007-2014 IOLA and Ole Laursen.

|
||||
|
||||
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.
