How to realize a pie chart with scroll bars

[marder]

Hi.

I want to implement a pie chart in Delphi with TeeChart Pro, which can be zoomed in.
When the chart is zoomed I would like to show scrollbars on the right and bottom axis, so that the user is able to see a certain part of the pie chart.

I did not find an easy way to do this.
Am I missing something, or do I really have to add TScrollbars to my panel and do all the scrolling stuff by myself?

Thank you in advance!
Best regards.

If you want is to change the TChart Aspect.Zoom/ZoomFloat, Aspect.HorizOffset/HorizOffsetFloat and Aspect.VertOffset/VertOffsetFloat properties, as you say, you could to it using ScrollBars.
Alternatively, you could use Mouse events in a similar way than TeeCommander does, when activating the Move and Zoom buttons in the component.
