| /* 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 thresholding data. | |
| Copyright (c) 2007-2013 IOLA and Ole Laursen. | |
| Licensed under the MIT license. | |
| 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. | |
