Having recently discovered the opensource plotting-software Veusz (http://home.gna.org/veusz/) I started playing around with it a bit.
Though limited to 2D plots, the formatting possibilities are quite impressive.
Not being a Programmer myself I successfully tried to export SMath data for formatting into Veusz and reimporting the Plot into SMath.
This works only for parametric plots exported as cvv-files. Functions have to be translated first into Veusz (Python) syntax and imported via an appropriate plugin.
A challenge for one of our many plugin programming experts .

See attached files (.vsz of course needs the program Veusz and is zipped for upload).

Nice, the main issue probably could be the license

Hello Ioan
thanks for your interest

Hw to obtain the plot ? and how to export it as png?

Having all my files locally I did not notice any difficulties. Now I found out that besides the format settings also the path and names of the datafiles are stored in the Veusz file. In this case of course the ones from me. Luckily this file is plain text. Just look at (and edit) the first few lines of Examples.vsz.

Sorry for the trouble

P.S. licence should be no problem. The program is "Free" and according to the homepage can be freely used in other software.

For all Linux users which unfortunately can't use the prize winning (gratuliere Kay ) Maxima plugin
for graphics, here a more serious and hopefully better documented example of a Veusz-plot.

To ensure compatibility between Windows and Linux, the screenshots in the tutorial have been included as png-images.

Hint: Text-regions which appear garbled due to the known SMath-bug under Linux can, at least teporarily,
be fixed by typing any letter and deleting it again.
