Re: [Webware-discuss] Charting libraries

[Winston W. <win...@ca...>]

Thanks for all the support on this issue.  I was really going nuts=20
trying to install all these different possiblities and always getting=20
stuck in some dark corner of configure/make hell.

Here were the suggestions I got:
	=95 Vitaliy Fuks, Cheng-Dae Choe - =
http://www.nullcube.com/software.html=20
- a Python interface to gdchart <http://www.fred.net/brv/chart/>
	=95 Adam Kerrison suggested pygdchart
	=95 Michael Palmer suggested=20
http://www.python.org/pypi?:action=3Ddisplay&name=3Dpaida&version=3D3.2.1_=
2.7=20
  Supposedly a pure python package.  But it only outputs SVG, PDF, EPS=20=

data and I wanted PNGs.
	=95 Tom Dennehy suggested R, an open-source version of the S+=20
statistical package. Excellent plotting capabilities from data in plain=20=

text files. Visit www.r-project.org.
	=95 Eduardo Elgueta - If you can spend some dollars, I recommend=20=

ChartDirector: http://www.advsofteng.com but they don't yet have a=20
Python-Mac OS X version.
	=95 Chris Barker - matplotlib has been easy on Linux and Windows =
for me.=20
All it needs in Numeric or numaray, if you are generating images for a=20=

web app, rather than a GUI.
	=95 Shayne O'Neill offered: GD (magic stuff!) and=20

I tried each one in turn and hit some stumbling block.  Finally I found=20=

PILChart by Richard Jones on Vaults of Parnasus, which only requires=20
Python Imaging Library (PIL).  There were some problems with PIL-1.1.4,=20=

but Richard's code was so simple and easy to understand, that I fixed=20
them quickly.  He is not updating his code anymore, so I have no place=20=

to put my fixes.  If there is interest, I will find a place to post a=20
new version of PILChart.

But first, I want to get the automated test cases finished for Webware.=20=

  Anybody want to lend a hand with the more tricky components like=20
WebKit, MiddleKit and Buildbot?
