Hello,

I am looking for scripts or libraries to produce sophisticated
heatmaps (from data-points in 2-dimensional grids) on the fly.
Examples of such heatmaps:

http://ww1.prweb.com/prfiles/2005/02/28/213516/cropped.jpg

The software would have to be in Java or in Coldfusion. In case no
such software exists also PHP, etc. would be acceptable. It must run
on Windows Servers however!

The software should be Open Source and/or free. Alternatively - if no
Open Source version exists - it may cost up to serveral hundred $.

Non-sophisticated results with binary structures (ie. clearly visible
steps, fixed visible grids) such as this one:
http://ploticus.sourceforge.net/gallery/gall.heatmap.html are NOT what
i'm looking for.

Thank you in advance!
Helge

Clarification of Question by helge01-ga on 16 Feb 2006 08:50 PST

I will cancel this question, as we solved the problem ourselves
meanwhile: We found a formula to extrapolate a sufficient number of
datapoints between those that we have. From that we use Flash to
create a nice graphic.
