 *
 * Usage:
 * $(selector).sparkline(values, options)
 *
 * If values is undefined or set to 'html' then the data values are read from the specified tag:
 * Sparkline: 1,4,6,6,8,5,3,5
 * $('.sparkline').sparkline();
 * There must be no spaces in the enclosed data set
 *
 * Otherwise values must be an array of numbers or null values
 * Sparkline: This text replaced if the browser is compatible
 * $('#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:
 * Sparkline: 
 * Sparkline: 
 * $('.sparkline').sparkline();
 *
 * For line charts, x values can also be specified:
 * Sparkline: 1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5
 * $('#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})
 * Sparkline: loading
 * 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
 * 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
 * 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)
 * 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

 * 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
 * barSpacing - Gap between bars in pixels
 * zeroAxis - Centers the y-axis around zero if true
 *
 * tristate - Charts values of win (>0), lose (<0) or draw (=0)
 * 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
 * thresholdColor

 * be computed for you. Default is false.
 * showOutliers - Set to true (default) to display outliers as circles
 * outlierIQR - Interquartile range used to determine outliers. Default 1.5
