First, thanks for your suggestion and I have made it zoom automaticly.
But, the lines can't recover after I have zoomed them in.
Is there any other event I should add to the tChart?

The version of the product is Teechart for .Net v3.
And, I checked the features demo based on your guide. But I have not found "Scrolling multiple axes". I am wondering that the product of this version doesn't support multiply axes.
