Hi,
I'm sure the solution to this is trivial, but I can't seem to find it.
I'm plotting a single polar plot on a page. Afterward, I'd like to
plot a series (P.MULTI style) of plots. I can get the first plot
to go fine. However, no matter what I seem to do the second page
of plots crashes with the error
Data coordinate system not established.
and all I get is a small bit of annotation in the upper right hand
corner of an otherwise empty page. This occurs even when I
try to plot only a single plot on the second page (e.g. !P.MULTI = 0).
Any suggestions as to what is happening and why? I've plotted
multiple pages of plots, multiple window plots before, and never
had a problem like this.
Thanks in advance for any suggestions!

Oh, setting that darn !P.Postion system variable
will play havoc with !P.Multi. :-)
Cheers,
David
P.S. Let's just say I *always* use the Position keyword
rather than the !P.Position system variable. It still
plays havoc, but it's easier to track down. :-)

Well, it seems to have been cleared up by a !P.POSITION = 0 command;
I assume that my polar plot routine did something *interesting* to
the window position information. :-}
I guess it was pilot error after all, eh?
