If you look at the CatCoord object in my Catalyst Library,
you will see that what is really needed is !X.CRANGE,
!X.S, and the !P.CLIP field. It took me nearly a year
to figure this out, and I paid dearly for the information,
but it is still easier to save all the plotting system
variables and be done with it. :-)
Cheers,
David

Indeed my first approach was plotting in a two column multi-plot. Then
I saw, that the data disappears outside the coordinate system in one of
the plots. So I tried two separate windows instead of the multi-plot.
Unfortunately with the same result.

Now I have learned from your example that it is not enough to save
!X.RANGE only, but the whole !X. Thanks!
Best regards

Thank you for this hint! /NODATA seems to be an easy way. But since I
would have to call PLOT too often, the program is slowed down. Thus the
trick of David Fanning might be the better choice in my case.

This is nearly identical to overploting with !P.MULTI

The secret is saving the correct system variables.

I'd make an invisible plot to setup my coordinate system, then perform
the PLOTS
plot, xvals, yvals, /nodata, xstyle=4, ystyle=4
plots, foobar
