Hi Peiyang,

You can get information about the selected point by listening to the ItemClick event. And then when the ItemClick event is fired use the ChartItemClickEventArgs to obtain the information you need.

//listen to the ItemClick event
radChart.DefaultView.ChartArea.ItemClick += ChartArea_ItemClick;

void ChartArea_ItemClick(object sender, ChartItemClickEventArgs e)
{
    double selectedPointX = e.DataPoint.XValue;
    double selectedPointY = e.DataPoint.YValue;

    //your code here...
}

I hope this helps. Kind regards,
