|

|
*
|
||
|
|
*
|
||
|
|
* 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)
