TeeChart Zoom and Panning Issue

votes

I have a dilemma. I am using the TeeChart in both zoom and panning mode.

When I pan the zoomed image to the right, I want the image to stay in its current horizontal position when I undo the zoom condition. However, when I do Chart1.UndoZoom, the image resets itself back to the left axis edge.

What am I doing wrong?

You could use Zoom.History:

  Chart1.Zoom.History := True;

This doesn't work combined with panning though. In which case, you could save desired axes minimum and maximum positions in OnZoom event and restore them in OnUndoZoom event.
