*
* Usage:
* $(selector).sparkline(values, options)
*
* If values is undefined or set to 'html' then the data values are read from the specified tag:
* <p>Sparkline: <span class="sparkline">1,4,6,6,8,5,3,5</span></p>
* $('.sparkline').sparkline();
* There must be no spaces in the enclosed data set
*
* Otherwise values must be an array of numbers or null values
* <p>Sparkline: <span id="sparkline1">This text replaced if the browser is compatible</span></p>
* $('#sparkline1').sparkline([1,4,6,6,8,5,3,5])
* $('#sparkline2').sparkline([1,4,6,null,null,5,3,5])
*
* Values can also be specified in an HTML comment, or as a values attribute:
* <p>Sparkline: <span class="sparkline"><!--1,4,6,6,8,5,3,5 --></span></p>
* <p>Sparkline: <span class="sparkline" values="1,4,6,6,8,5,3,5"></span></p>
* $('.sparkline').sparkline();
*
* For line charts, x values can also be specified:
* <p>Sparkline: <span class="sparkline">1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5</span></p>
* $('#sparkline1').sparkline([ [1,1], [2.7,4], [3.4,6], [5,6], [6,8], [8.7,5], [9,3], [10,5] ])
*
* By default, options should be passed in as the second argument to the sparkline function:
* $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
*
* Options can also be set by passing them on the tag itself. This feature is disabled by default though
* as there's a slight performance overhead:
* $('.sparkline').sparkline([1,2,3,4], {enableTagOptions: true})
* <p>Sparkline: <span class="sparkline" sparkType="bar" sparkBarColor="red">loading</span></p>
* Prefix all options supplied as tag attribute with "spark" (configurable by setting tagOptionsPrefix)
*
* Supported options:
* lineColor - Color of the line used for the chart
* fillColor - Color used to fill in the chart - Set to '' or false for a transparent chart
* width - Width of the chart - Defaults to 3 times the number of values in pixels
* height - Height of the chart - Defaults to the height of the containing element
* chartRangeMin - Specify the minimum value to use for the Y range of the chart - Defaults to the minimum value supplied
* chartRangeMax - Specify the maximum value to use for the Y range of the chart - Defaults to the maximum value supplied
* chartRangeClip - Clip out of range values to the max/min specified by chartRangeMin and chartRangeMax
* chartRangeMinX - Specify the minimum value to use for the X range of the chart - Defaults to the minimum value supplied
* chartRangeMaxX - Specify the maximum value to use for the X range of the chart - Defaults to the maximum value supplied
* composite - If true then don't erase any existing chart attached to the tag, but draw
* another chart over the top - Note that width and height are ignored if an
* existing chart is detected.
* tagValuesAttribute - Name of tag attribute to check for data values - Defaults to 'values'
* enableTagOptions - Whether to check tags for sparkline options
* tagOptionsPrefix - Prefix used for options supplied as tag attributes - Defaults to 'spark'
* disableHiddenCheck - If set to true, then the plugin will assume that charts will never be drawn into a
* hidden dom element, avoding a browser reflow
* disableInteraction - If set to true then all mouseover/click interaction behaviour will be disabled,
* making the plugin perform much like it did in 1.x
* disableTooltips - If set to true then tooltips will be disabled - Defaults to false (tooltips enabled)
* disableHighlight - If set to true then highlighting of selected chart elements on mouseover will be disabled
* defaults to false (highlights enabled)
* highlightLighten - Factor to lighten/darken highlighted chart values by - Defaults to 1.4 for a 40% increase
* tooltipContainer - Specify which DOM element the tooltip should be rendered into - defaults to document.body
* tooltipClassname - Optional CSS classname to apply to tooltips - If not specified then a default style will be applied
* tooltipOffsetX - How many pixels away from the mouse pointer to render the tooltip on the X axis
* tooltipOffsetY - How many pixels away from the mouse pointer to render the tooltip on the r axis
* tooltipFormatter - Optional callback that allows you to override the HTML displayed in the tooltip
* callback is given arguments of (sparkline, options, fields)
* tooltipChartTitle - If specified then the tooltip uses the string specified by this setting as a title
* tooltipFormat - A format string or SPFormat object (or an array thereof for multiple entries)
* to control the format of the tooltip
* tooltipPrefix - A string to prepend to each field displayed in a tooltip
* tooltipSuffix - A string to append to each field displayed in a tooltip
* tooltipSkipNull - If true then null values will not have a tooltip displayed (defaults to true)
* tooltipValueLookups - An object or range map to map field values to tooltip strings
* (eg. to map -1 to "Lost", 0 to "Draw", and 1 to "Win")
* numberFormatter - Optional callback for formatting numbers in tooltips
* numberDigitGroupSep - Character to use for group separator in numbers "1,234" - Defaults to ","
* numberDecimalMark - Character to use for the decimal point when formatting numbers - Defaults to "."
* numberDigitGroupCount - Number of digits between group separator - Defaults to 3
*
* There are 7 types of sparkline, selected by supplying a "type" option of 'line' (default),
* 'bar', 'tristate', 'bullet', 'discrete', 'pie' or 'box'
* line - Line chart. Options:
* spotColor - Set to '' to not end each line in a circular spot
* minSpotColor - If set, color of spot at minimum value
* maxSpotColor - If set, color of spot at maximum value
* spotRadius - Radius in pixels
* lineWidth - Width of line in pixels
* normalRangeMin
* normalRangeMax - If set draws a filled horizontal bar between these two values marking the "normal"
* or expected range of values
* normalRangeColor - Color to use for the above bar
* drawNormalOnTop - Draw the normal range above the chart fill color if true
* defaultPixelsPerValue - Defaults to 3 pixels of width for each value in the chart
* highlightSpotColor - The color to use for drawing a highlight spot on mouseover - Set to null to disable
* highlightLineColor - The color to use for drawing a highlight line on mouseover - Set to null to disable
* valueSpots - Specify which points to draw spots on, and in which color. Accepts a range map
*
* bar - Bar chart. Options:
* barColor - Color of bars for postive values
* negBarColor - Color of bars for negative values
* zeroColor - Color of bars with zero values

* can be an Array of values to control the color of individual bars or a range map
* to specify colors for individual ranges of values
* barSpacing - Gap between bars in pixels
* zeroAxis - Centers the y-axis around zero if true
*

* posBarColor - Color of win values
* negBarColor - Color of lose values
* zeroBarColor - Color of draw values
* barWidth - Width of bars in pixels
* barSpacing - Gap between bars in pixels
* colorMap - Optional mappnig of values to colors to override the *BarColor values above
* can be an Array of values to control the color of individual bars or a range map
* to specify colors for individual ranges of values
*
* discrete - Options:
* lineHeight - Height of each line in pixels - Defaults to 30% of the graph height
* thesholdValue - Values less than this value will be drawn using thresholdColor instead of lineColor
