Thx. I didn't know these programs. Looks great. I will try it.

I have put sorce code on file page ( if you don't mind it ).

I'm using maxima and gnuplot. Can you compare it with your programs ?

If you like you can :

move it to commons ,
make new category ( in commons) like in gnuplot and maxima case :
- Category:Gnuplot_diagrams
- Category:Created with Maxima (software)
ad new categories to your's image page

Do you know Visualizing Conformal Maps by Michael J. Gruber ? --Adam majewski (talk) 15:58, 9 December 2008 (UTC)[reply]

I don't see a need to upload this to commons since it was just intended to answer a question on the reference desk. I'm not too familiar with gnuplot, sorry. I might have seen that web page before. Fredrik Johansson 16:47, 9 December 2008 (UTC)[reply]
