I've tried Excel, Cricket Graph for Mac, SigmaPlot and Gnuplot. Either
of these programs does what I realy want, and most of them fail to write
proper encapsulated postscript (excpet for gnuplot off course). I'm
writing up my thesis and take the opportunity to learn a little bit
about R - I'm sure it'll be very useful for me once I've learned the
basic stuff.

Ahh, the mar option seems to be exaclty what I'm looking for, just tired
it (successfully ;-). Very good!
But now I've another problem - thelegend of the plot. By default it's
placed in the upper right corner, and I've managed to place it where I
want (e.g. just below the plot using 'horiz'). Unfortunately I cannot
get the sourrounding box for the legend and the small coloured boxes for
the legend, alothough I'm using the 'filled' option.

Ok, I'm not usre what's the best way to send thge code + data but
here's
basically what I've done:
mx is my data matrix from which I'd like to produce a stacked bar chart.

The legend labels appear correctly but the symbols don't (no symbols at
all). I thought if the filled argument is set small squares are
displayed ... . The problem is that one does not know which bar colours
belongs to which category.
I'm using R 1.1.1 under Suse linux 7.1.
Maybe you've got an idea what goes wrong here. Thanks again for a lot
for your kind help.
regards,
Arne
