在我的温Forms申请中,我有对这些情况的图表控制:
chartArea.CursorX.IsUserEnabled = true;
chartArea.CursorX.IsUserSelectionEnabled = true;
chartArea.AxisX.ScaleView.Zoomable = false;

What I am trying to do is posibility of selecting area (it is possible already), and when mouse is over this area, if I left click chart cotrol inside that selected area, I wan t it too zoom in.
First problem here is how to detect if I am over selected area ? with chart.HitTest() i can get HitTestResult.PointIndex field value and compare it with selection range. But this only works, if mouse is exactly over DataPoint. So it doesn t work for SeriesChartType.FastLine which I am using.
如果能解决这种问题,则在点燃后(在<条码>Click/ 代码>或<代码>MouseXXX上)取消甄选问题。

I ve found axis.PixelPositionToValue() method, which gives me every info I need, because from MouseMove event arguments I have pixel position.
For click events problem I ll write another question.
