[gradsusr] scatter plot: how to change markers and colors?

[Henrique Barbosa]

Dear all,

I need to plot different data sets on the same scatter plot. That's easy...
but how do I control which color and marker are used
for each display command? I searched the archive but didn't find
the answer.

I tried to get everything red by:

set ccolor 2
set line 2
set lfcols 2 2
set wxcols 2 2 2 2 2 2
set clopts 2

but nonthing works... Grads always varies the markers and their
colors in its own way. Is it possible to control that?

Thanks,
Henrique
