How to select the first pie in bar chart?

[Huang-Libo]

I know the delegate 'chartValueSelected' , however it's called when user touches the bar chart, now I need the bar chart's first pie to be highlighted by defaul.

[liuxuan30]

manually create ChartHighlight objects and pass to chart, or check out highlightValue() in ChartViewBase

I finally found a method to do this job :

• (void)highlightValueWithXIndex:(NSInteger)xIndex dataSetIndex:(NSInteger)dataSetIndex callDelegate:(BOOL)callDelegate;
