historical un-zooming does not work on saved zoomed state

[amol]

Hi,

We are using the feature of historical un-zooming in our application. We have a requirement that if user zooms the chart 2-3 times, application can save this state which can be used for future; In this case when we apply the saved state later to get the exact zoomed state (which we saved in a text file and we apply it by setting the min and max axis), then historical unzoom in this case does not works. It seems that when the application is closed and opened the next time and saved state is applied, tchart does not remembers the zooming done.
Please guide us as to how we may get the historical un-zooming to be working in this scenario.

Regards,
Bhanu

Hello amol,

Could you send us a simple application because we can reproduce the problem here and we try to find a solution for the problem?

Thanks in advance
