Dear Mathias,

You might try a simple program like MOPLOT from the institute of physikal
chemistry here in Fribourg. It runs on a PC. For more details see
http://sgich1.unifr.ch/pc/moplot.html

or download it by ftp:

"How to obtain MOPLOT

MOPLOT can be copied from the anonymous ftp archive on 
sgpch1.unifr.ch where it is located in the
/moplot directory. It is free of charge. 
The authors would be grateful to learn about your opinion on
MOPLOT and possible bugs in the program. "

Regards,
Olivier
