  Thanks for taking the time to read my post! :)

 It's worth checking out matplotlib as well although it may not meet all
 your criteria ... but have a look, its a great package

PyX might also be interesting, depending on your needs.

While pyx is a very nice package, it is probably not a good choice for
web app developers simply because it generates postscript, which is
not very browser friendly.  Once could send the PS through a converter
such as ImageMagick, but it would probably be better to use a library
that generates browser friendly output natively.

matplotlib on the other hand, *does* work in web app servers, and
generates PNG/SVG natively.  See
http://matplotlib.sourceforge.net/faq.html#APPSERVER

Although it is a free and open source package, I think that the image
quality and support is on par with if not superior to what you find in
many commercial solutions.  If the OP wants commercial support, he
might consider contacting the developer off-list :-)

Amen to that. The ChartDirector demos looked very ugly to my eye. 
matplotlib plots usually look quite good without any tweaking.

 I don't understand what you're talking about. I've been using GRACE in
 batch mode for years and I've never had a window pop up. The only time
 a window pops up is when you start GRACE interactively.

Hmm, I guess I was actually using grace_np.py rather than batch
mode... it was a few years ago I last used it.


 The GRACE command language is not the greatest, but it gets the job
 done. It may have improved lately too (I run a fairly old version).
 
 Another nice feature of GRACE is a fairly active user community and a
 mailing list for help. They helped get me unstuck several times a while
 back.

...and some nasty features are the rather nasty GUI (at least, I found
it awkward) and the fact that it's the only X11 application I've used
that ever managed to crash my whole X desktop.

We use both the Python and C++ bindings of ChartDirector (although their 
license always spans /all/ supported bindings. It's all pretty 
straight-forward, well-documented, and the license fee is a bargain 
compared to other packages we've used in the past. What it is not 
suitable for is maybe allowing for 3d-views of data cubes - changeable 
on the fly.

Check out GRACE. It's not specifically designed for Python, but I've
been using with Python for a couple of years or more. I'm very happy
with it, and it's free. It works both interactively and in batch mode.
Do a google on GRACE.

If you're generating lots of graphs programatically, eg. on a web
server, grace is not what you want.  Yes, it has a command language,
but IIRC it depends on X11, and windows even pop up as it runs in
batch mode.  Bleh.

Gets the job done for interactive editing of publication-quality
scientific graphs, though.

I have used ChartDirector extensively as an activeX (not from

The tool is definitely worth the value. Simple to use and productive.
It saved us a lot of time. A great product.

Commerical graphing packages?

2005-02-11 Thread Erik Johnson

I am wanting to generate dynamic graphs for our website and would rather
not invest the time in developing the code to draw these starting from
graphics primitives. I am looking for something that is... fairly robust
but our needs are relatively modest: X-Y scatter plots w/ data point
symbols, multiple data set X-Y line plots, bar charts, etc.

Preferably this would come from a company that can provide support 
decent documentation, and a package that can be installed without a bunch of
extra hassle (e.g., needs Numeric Python, needs to have the GD library
installed, needs separate JPEG encoders, font libraries, etc.)

I am aware of ChartDirector (http://www.advsofteng.com/ ) which
explicitly supports python and seems to be about the right level of
sophistication. I don't really know of any other packages in this space, do
