* <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 teh 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 tagOptionPrefix)
-*
* 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
* 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
-* tagOptionPrefix - 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)
* 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)
* 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
+* There is 1 type of sparkline, selected by supplying a "type" option of 'bar' (default),
*
* bar - Bar chart. Options:
* barColor - Color of bars for postive values
* zeroColor - Color of bars with zero values
