-* v1.6
-* (c) Splunk, Inc
-* Contact: Gareth Watts (gareth@splunk.com)
-* http://omnipotent.net/jquery.sparkline/
-*
-* Generates inline sparkline charts from data supplied either to the method
-* or inline in HTML
-*
-* Compatible with Internet Explorer 6.0+ and modern browsers equipped with the canvas tag

-*
-*
-* 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 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
-* 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'
-*
-* 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

-* 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

-* can be an Array of values to control the color of individual bars
-* 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
-*
-* 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
-*
-* bullet - Values for bullet graphs msut be in the order: target, performance, range1, range2, range3, ...
-* options:
-* targetColor - The color of the vertical target marker
-* targetWidth - The width of the target marker in pixels
-* performanceColor - The color of the performance measure horizontal bar
-* rangeColors - Colors to use for each qualitative range background color
-*
-* pie - Pie chart. Options:
-* sliceColors - An array of colors to use for pie slices
-* offset - Angle in degrees to offset the first slice - Try -90 or +90
-*
-* box - Box plot. Options:
-* raw - Set to true to supply pre-computed plot points as values
-* values should be: low_outlier, low_whisker, q1, median, q3, high_whisker, high_outlier
-* When set to false you can supply any number of values and the box plot will
-* be computed for you. Default is false.
-* showOutliers - Set to true (default) to display outliers as circles
-* outlierIRQ - Interquartile range used to determine outliers. Default 1.5
-* boxLineColor - Outline color of the box
-* boxFillColor - Fill color for the box
-* whiskerColor - Line color used for whiskers
-* outlierLineColor - Outline color of outlier circles
-* outlierFillColor - Fill color of the outlier circles
-* spotRadius - Radius of outlier circles
-* medianColor - Line color of the median line
-* target - Draw a target cross hair at the supplied value (default undefined)
-*
-*
-*
-* Examples:
-* $('#sparkline1').sparkline(myvalues, { lineColor: '#f00', fillColor: false });
-* $('.barsparks').sparkline('html', { type:'bar', height:'40px', barWidth:5 });
-* $('#tristate').sparkline([1,1,-1,1,0,0,-1], { type:'tristate' }):
-* $('#discrete').sparkline([1,3,4,5,5,3,4,5], { type:'discrete' });
-* $('#bullet').sparkline([10,12,12,9,7], { type:'bullet' });
-* $('#pie').sparkline([1,1,2], { type:'pie' });
