The question is: why do you think there should be another
charting/graphing library? Do you have problems with the
JFreeChart license (LGPL)?
You could go shopping around for other libraries, there are
at least 50 open source libs for Java and C# on sourceforge,
some using BSD or MIT license. For an ASL licensed library,
checv out krysalis wings http://www.krysalis.org/wings/,
although the project seems to be dead too.

This could be interesting, Henri.  If we had an formal description of a
project, providing its name, resource (www, scm, wiki, etc.) locations,
ontological classifications, etc., I imagine that could be useful in
producing a portal.
Sounds awfully close to a Maven project.xml.
We would want some nice means for aggregating and dynamically managing the
data, but fortunately we have a ready standard for dealing with the content:
LDAP.

The nice thing about standards is that there are so many to choose from.

There are also RDF/RSS/DC and a variety of other XML based metadata
languages (Topic Maps would fit almost as well as LDAP).

Hm, could you give a more detailed list of features you expect?
E.g.:
- input data structure and format (is it a file?)
- what statistics? fitting curves? clustering? calculating
 medians, standard derivations, quantiles, rankings? test
 for abnormal data?
- what nice graphs? lines, bars, different markers, candles, 3D?
- just plot or do user interaction: zoom in etc?

Hi.

JMeter could make good symbiosis with a free Java data analysis tool. 
I've been searching a little, but not been able to find anything good.

Most relevant requirements are being able to read a set of numeric timed 
data sets and generate nice graphs and simple statistics from them.

Any pointers?

Hm. Statistics: jakarta-commons-math. Nice graphs: jFreeGraph or
whatever else you can grab from sourceforge (there are at least
3 mature projects).
Get the plumbing and UI is still work though. :-/

Might it perhaps make sense to scrub or obsucure email

There was an article on slashdot mentioning a study about
how spammers get the addresses. Basically scraping web
pages mailto links and strings looking like email addresses
seems to be the most used technology. They stated that even
simple obfuscations like using HTML entities or character
references will cut spam sent to these addresses drastically,
while they are still fully functional as mailto links.
Apparently they scan web pages as text, not HTML. Other ideas
include strange looking account names containing odd but
nevertheless valid characters which throw the scanners off.
Unfortunately, Yahoo et al. usually wont accept them either.
More advanced JavaScript based techniques or, if the address is
for information rather than a mailto link, using j3322ptm at
yahoo dot com will be successful in cuttting down spam for some
time to come, until word gets around and the spammers run out of
easy prey and start using HTML parsers, JavaScript engines and
advanced pattern matching.
