Welcome to IWETHEY!

New I use gnuplot for my charting.
gnuplot is a script-based plotting package. http://www.gnuplot.info

There is a python interface for it, and I think a perl interface as well (but I won't swear to it). It's extremely flexible for constructing graphics (even publication-quality), especially when using the PostScript "terminal".

There is a bit of a learning curve with it, and it might be overkill for your needs, but lots of examples are available - http://gnuplot.sourceforge.net/demo_4.2/

HTH.

Cheers,
Scott.
New Any pie charts in there?
New Sure.
gnuplot doesn't do pie charts out of the box, but it's not hard to roll your own:

http://gnuplot-trick...with-gnuplot.html
http://gnuplot-trick...e-chart-with.html

But you probably don't really want to use a pie chart anyway - http://www.usf.uni-o...piecharts.en.html ;-)

As an example of using gnuplot with a database, this might be helpful - http://www.linux.com...th-gnuplot-part-3 - I haven't done anything like that myself.

HTH a little.

Cheers,
Scott.
New Not hard?
Ok, we have levels of pain in this thread.
Those gnuplot scripts move in desade territory.
New Yeah, it's a little obtuse.
gnuplot is a 24-year old program that is maintained via patches (the original copyright and license requires that - http://gnuplot.cvs.s...right?view=markup ).

A newer package that uses similar script syntax as gnuplot but is much more friendly to extension is pyxplot (and it includes pie charts) - http://pyxplot.org.u...bution/index.html [Thanks for giving me the incentive to look into this - pyxplot looks like a very nice package, though it uses LATeX and would have a learning curve for me.]

gnuplot fits with the way I work, but has a learning curve.

I see there's a CPAN module for doing gnuplot charts with perl, and a pie chart module for that - http://kobesearch.cp.../Gnuplot/Pie.html That seems like a nice package, but I haven't used it myself, and I can't find an example.

Another package that might fit your needs better than gnuplot is matplotlib for python. It does pie charts out of the box.

http://matplotlib.so...les/pie_demo.html

Since it does more out of the box, it's a bigger package with more dependencies, but prebuilt binaries are available. http://matplotlib.so...s/installing.html

Whether it's a good fit for you, I can't say. But it does plotting very very well.

HTH a little.

Cheers,
Scott.

Of course the Satanists don't bother me any more ever since they did a background check on me and discovered I had three sixes in my birthdate.
