I will leech on the thread as it's of intrest to me too.

What parasonic wants is to be able to set the axis to arbitrary range without affecting how the plot is rendered.
That's exacly what I'm trying to do.
Suggestion made by FelixB would probably work if you don't need top axis, if you do - that's no-go.

So for example if plot item is build from points which x range is 0-100 how to set the axis to be 50-392 (or 0.001 to 0.107 etc) without affecting how the plot is displayed (zoomer has to work in that setup as well)?
