Re: plotting problems

[Matt Funk]

What Dmitri suggested worked for the problem that i described in the email. 
the only thing is that later on i wanted to write contents of the different 
plots out to a .png file. 
for that it unfortunately didn't work anymore. so i resolved to simply write 
the stuff out to a file, load it back later and plot it.

thanks for the suggestions and help
