Give the opportunity to pass an url of an xml to highcharts with the datas for the chart.
The datas will be the categories of an axis and the data of a series.
Something like this:
<datas>
<data>
<series>0,1,2,...</series>
<categories>0,1,2,...</categories>
</data>
<data>
<series>3,4,5,...</series>
<categories>1,2,3,...</categories>
</data>
</datas>
This feature would help the implementation of libraries with other programming languages like php, asp, asp.net, ...
The programmer should not implement functions in js to interpret the data, but simply pass the URL of the XML and highcharts will parsing it.
