* About: Introduction
*
* jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.1 is included in the distribution.
* To use jqPlot include jQuery, the jqPlot jQuery plugin, the jqPlot css file and optionally
* the excanvas script for IE support in your web page:
*
* > <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
* > <script language="javascript" type="text/javascript" src="jquery-1.4.2.min.js"></script>
* > <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
* > <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
*
* jqPlot can be customized by overriding the defaults of any of the objects which make
* up the plot. The general usage of jqplot is:
*
* > chart = $.jqplot('targetElemId', [dataArray,...], {optionsObject});
*
* The options available to jqplot are detailed in <jqPlot Options> in the jqPlotOptions.txt file.
*
* An actual call to $.jqplot() may look like the
* examples below:
*
* > chart = $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]);
*
* or
*
* > dataArray = [34,12,43,55,77];
* > chart = $.jqplot('targetElemId', [dataArray, ...], {title:'My Plot', axes:{yaxis:{min:20, max:100}}});
*

/**
* Class: $.jqplot.ThemeEngine
* Theme Engine provides a programatic way to change some of the more
* common jqplot styling options such as fonts, colors and grid options.
* A theme engine instance is created with each plot. The theme engine
* manages a collection of themes which can be modified, added to, or
* applied to the plot.
*
* The themeEngine class is not instantiated directly.
* When a plot is initialized, the current plot options are scanned
* an a default theme named "Default" is created. This theme is
* used as the basis for other themes added to the theme engine and
* is always available.
*
* A theme is a simple javascript object with styling parameters for
* various entities of the plot. A theme has the form:
*
*
* > {
* > _name:f "Default",
* > target: {
* > backgroundColor: "transparent"
* > },
* > legend: {
* > textColor: null,
* > fontFamily: null,
* > fontSize: null,
* > border: null,
* > background: null
* > },
* > title: {
* > textColor: "rgb(102, 102, 102)",
* > fontFamily: "'Trebuchet MS',Arial,Helvetica,sans-serif",
* > fontSize: "19.2px",
* > textAlign: "center"
* > },
* > seriesStyles: {},
* > series: [{
* > color: "#4bb2c5",
* > lineWidth: 2.5,
* > shadow: true,
* > fillColor: "#4bb2c5",
* > showMarker: true,
* > markerOptions: {
* > color: "#4bb2c5",
* > show: true,
* > style: 'filledCircle',
* > lineWidth: 1.5,
* > size: 4,
* > shadow: true
* > }
* > }],
* > grid: {
* > drawGridlines: true,
* > gridLineColor: "#cccccc",
* > gridLineWidth: 1,
* > backgroundColor: "#fffdf6",
* > borderColor: "#999999",
* > borderWidth: 2,
* > shadow: true
* > },
* > axesStyles: {
* > label: {},
* > ticks: {}
* > },
* > axes: {
* > xaxis: {
* > borderColor: "#999999",
* > borderWidth: 2,
* > ticks: {
* > show: true,
* > showGridline: true,
* > showLabel: true,
* > showMark: true,
* > size: 4,
* > textColor: "",
* > whiteSpace: "nowrap",
* > fontSize: "12px",
* > fontFamily: "'Trebuchet MS',Arial,Helvetica,sans-serif"
* > },
* > label: {
* > textColor: "rgb(102, 102, 102)",
* > whiteSpace: "normal",
* > fontSize: "14.6667px",
* > fontFamily: "'Trebuchet MS',Arial,Helvetica,sans-serif",
* > fontWeight: "400"
* > }
* > },
* > yaxis: {
* > borderColor: "#999999",
* > borderWidth: 2,
* > ticks: {
* > show: true,
* > showGridline: true,
* > showLabel: true,

* > fontWeight: null
* > }
* > },
* > x2axis: {...
* > },
* > ...
* > y9axis: {...
* > }
* > }
* > }
*
* "seriesStyles" is a style object that will be applied to all series in the plot.
* It will forcibly override any styles applied on the individual series. "axesStyles" is
* a style object that will be applied to all axes in the plot. It will also forcibly
* override any styles on the individual axes.
*
* The example shown above has series options for a line series. Options for other
* series types are shown below:
*
* Bar Series:

/**
* JavaScript printf/sprintf functions.
*
* This code has been adapted from the publicly available sprintf methods
* by Ash Searle. His original header follows:
*
* This code is unrestricted: you are free to use it however you like.
*
* The functions should work as expected, performing left or right alignment,
* truncating strings, outputting numbers with a required precision etc.
*
* For complex cases, these functions follow the Perl implementations of
* (s)printf, allowing arguments to be passed out-of-order, and to set the
* precision or length of the output based on arguments instead of fixed
* numbers.
*
* See http://perldoc.perl.org/functions/sprintf.html for more information.
*
* Implemented:
* - zero and space-padding
* - right and left-alignment,
* - base X prefix (binary, octal and hex)
* - positive number prefix
* - (minimum) width
* - precision / truncation / maximum width
* - out of order arguments
*
* Not implemented (yet):
* - vector flag
* - size (bytes, words, long-words etc.)
*
* Will not implement:
* - %n or %p (no pass-by-reference in JavaScript)
*
* @version 2007.04.27
* @author Ash Searle
*
* You can see the original work and comments on his blog:
* http://hexmen.com/blog/2007/03/printf-sprintf/
* http://hexmen.com/js/sprintf.js

/**
* @Modifications 2009.05.26
* @author Chris Leonello
*
* Added %p %P specifier
* Acts like %g or %G but will not add more significant digits to the output than present in the input.
* Example:
* Format: '%.3p', Input: 0.012, Output: 0.012
* Format: '%.3g', Input: 0.012, Output: 0.0120
* Format: '%.4p', Input: 12.0, Output: 12.0
* Format: '%.4g', Input: 12.0, Output: 12.00
* Format: '%.4p', Input: 4.321e-5, Output: 4.321e-5
* Format: '%.4g', Input: 4.321e-5, Output: 4.3210e-5
