Hallo Werner,
Thanks for your solution, it is working better with plspage(). Somehow I did
not notice that function when browsing through the different methods of
setting up the plot window... But maybe the documentation could be altered
slightly:
plspage (xp, yp, xleng, yleng, xoff, yoff);
xp (PLFLT, input) Number of pixels, x.
yp (PLFLT, input) Number of pixels, y.
xleng (PLINT , input) Page length, x.
yleng (PLINT, input) Page length, y.
xoff (PLINT, input) Page offset, x.
yoff (PLINT, input) Page offset, y.
The first two should maybe not say "Number of pixels", but something like
"Pixels per inch, x"
and maybe the variable names should be xdpi and ydpi (not really important).
The second pair could be
"Number of pixels, x" or "Page length (pixels), x"
The last pair could maybe be something like
"Page offset (pixels), x".
Best regards,
Torquil Sørensen
