Hi,
I'm quite new to python and matplotlib, but at least simple graphs work
already. But now I tried to use tex for processing labels.
tex, latex, dvipng and ghostscript are in my path. A manual tex-run on
the tex file produces a dvi file.
Any help is appreciated
Wolfgang
PS: I'm runnin on WinXP prof
