[Gnuplot-py-users] choose the color

Hi everybody, 
I'm trying to change the color of a function... and I can't.
I used to call, for example:
gnuplot -xrm 'gnuplot*line2Color:yellow', 

but, of course I can't do this now, so
how can I do it?

One more thing. I can't change the file .Xdefaults because I'm not the system
administrator.

Thank you very much...
at least there's somebody on the other side... ;)
Albert
