+* 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>

+*
+* 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)

+* 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)

+* 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
