Map Series and Zoom

Post by Peeryog » Mon Jun 06, 2022 10:17 pm

Just getting used to the map series and I hope there is a simple answer,
The zoom and scroll function work great, until I add some code to the OnSeriesClick event. Then that code takes precedence and the zoom function fails to start. This would be on a map , say, and the user is clicking on a state or province and in this case it is desired that clicking anywhere in the polygon that represents the state will perform the OnSeriesClick event.

Is this the behaviour I should expect to see?

Best Regards

Hello Peter,

Indeed, the event is capturing the action and not propagating the event.
If you want to change this behaviour, you can set CancelMouse property to False:

Code: Select all

procedure TForm1.Chart1ClickSeries(Sender: TCustomChart; Series: TChartSeries;
  ValueIndex: Integer; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
