Sure, you can store the scrolling and scaling variables in some temporary location. Then, when you need to undo the zooming/scrolling set the axis scrollscale scroll and zoom to those stored variables.

Hi,

Very Good article,after zooming,is there any way to undo my latest change..

No, the feature request page is still the same. I made an attempt to write a code sample. It's not exactly perfect, but hopefully will prove useful.

Hi Max,  I did that and I also have purchased infragistics license with standard support. Do I need to submit this request on a different link since I have the standard support? Thanks.
