+*
+* 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
+* <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])
+*
+* 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] ])
+*
+* 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 range of the chart - Defaults to the minimum value supplied
+* chartRangeMax - Specify the maximum value to use for the 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.
+*
+* 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
+* 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
+* defaultPixelsPerValue - Defaults to 3 pixels of width for each value in the chart
+*
+* bar - Bar chart. Options:
+* barColor - Color of bars for postive values
+* negBarColor - Color of bars for negative values
+* barWidth - Width of bars in pixels
+* 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
+*
+* 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' });
