yes it seems to be

If you want to end up with a PDF plot, use pdf() and set the various

we plot the graphs on the postscript device (because on the server I work
X11 is unfortunately not available), and after we copy from postscript
device to both pdf (dev.copy) and bitmap (dev2bitmap) device (.png file at
the end).
So the graphs look OK on png image but not on the pdf ; I will try to set
parameters on pdf()

One other possibility, just to throw it out there since you are on

Thanks for this, I already used 'ps2pdf' before, but in this way I can't
because:
- I do several graphics in the script, each of them is "drawn" on the
postscript device, copied to bitmap and pdf, then the postscript device is
shut down but not the pdf one, which presents all the graphics in one file
(several pages) at the end.
- the script has to be a "cross platform" one...


Thanks again, I try settings on pdf() and tell you,

Florence.
