How to Undo Zoom on a WebChart using a zoom tool

Hi,
I need to supply zoom functionality on my WebChart.
I used you sample code to add a zoom tool that would let me select a rectangle on the chart and zoom on it, which worked fine.

In the ActiveX TeeChart version, drawing a rectangle in the opposite direction,
(dragging the mouse, starting on lower right and going up to upper left and releasing)
Resulted in Undo Zoom (returning to original state of the graph)
How do I support the same functionality in the .net version?

Hi MeirS,

The same behavior as in the ActiveX version should work with WebChart. Which TeeChart version are you using? Are you referring to the example in the ASP.NET demo or some example we arranged for you?

Thanks in advance.
