Hi Simona,
I would like to emphasize what was said by Jeremy & David
(just to make sure the point is not going to be missed):
Please do *not* plot something on window 1, plot something on window
2,
then go back to 1 and do an overplot.
This will most likely have disastrous consequences and give you
a headache. I'd rather suggest you go swimming with sharks if
you really like the thrill of doing something dangerous :)
There are 3 ways of doing this properly:
1) (perhaps the simplest solution) switch the order of the plots
plot on 1, oplot on 1, plot on 2
(you can accomplish this by saving the x and y position of the
datapoints and only plotting when all is computed)
2) save and restore the graphic coordinates for each window
plot on 1, save graphic coord of 1, plot on 2, restore graph coord
of 1, oplot on 1
I would suggest not to do that as it is somewhat complicated.
3) use cg* routines as described by David & Jeremy
Ciao,
Paolo
