The point was that the OP > wants something that only needs Python. matplotlib can be used to generate .ps, .pdf and .svg files (all vectorial formats) without resorting to Antigrain Antigrain is used only in rasterizing, due to its better capabilities in the field of antialiasing, when you use matplotlib with an interactive backend; of course, if you're truly dispising Antigrain and are happy with a coarser display you can select interactive backends that DO NOT use Antigrain that's for the Antigrain wrapper otoh, if the OP intended a plotting library that does not use binary modules at all (then his reference to Antigrain was mostly fogging), then matplotlib is not for him % find matplotlib-0.99.0/| grep -v agg24 | grep '\.cpp$' | wc -l 23 % find matplotlib-0.99.0/| grep -v agg24 | grep '\.c$' | wc -l 5 % -- I wish we'd come to our senses and see there is no truth In those who promote the confusion for this ever changing mood. (people get ready people get ready people get ready people get ready)

AFAIK, when building Python from sources, tcl/tk support has always been optional as well. -- Grant Edwards grante Yow! Being a BALD HERO at is almost as FESTIVE as a visi.com TATTOOED KNOCKWURST.

It can plot charts I think, though last time I used it I plotted stuff by hand as I wanted exact control over the layout. I'm not sure of the dependencies though so may not be suitable for your purposes. http://www.reportlab.org/rl_toolkit.html -- Nick Craig-Wood <nick(a)craig-wood.com> -- http://www.craig-wood.com/nick |
