Hi,

it is possible to zoom in by dragging a rectangle from top left to bottom right. However, any "negative" rectangle will undo all zoom.

Is it possible to zoom by dragging a rectangle from any other corner (top right to bottom left, bottom left to upper right, bottom right to upper left)?

If not, what should I implement in order to have such a feature?

Thanks

Hi Qwerty,

Yes, you could try disabling standard zooming features:
And then use ZoomRect:
You could define the rectangle using TChart's mouse events: MouseDown, MouseUp, etc.

Hope this helps!
