We are running perl 5.8.5 on a Linux machine that is running

with mod_perl 2.0.3. Our data is in a MySQL database (MySQL 5.0.45)
We have been asked to write a web application that requires plotting
capabilities. We do most of our web programming in perl so I am
looking
for a perl module that has the following features: 1. ability to
create
histograms
2. ability to create x,y plots
3. ability to zoom in on a portion of the graph
4. ability to calculate the distance between 2 points on the graph
5. ability to hover on a point and bring up some text
Does anyone have any suggestions for which perl modules we should
look
into?
To make your life easier, use a third-party Flash charting tool. It's
pretty and it's more interactive than a static jpg (for example).
The role of Perl in this case is simply to generate the data for the
flash application to load. Most of the time it's an XML document, so
that's something Perl does very well.
I'e used Visual Engineering's KavaChart <http://www.ve.com/kavachart/index.html/
> to do 1, 2, 3, and 5 above. It may do 4, but I haven't tried
anything like that with it. I have code for a simple System Load
application listed at <http://www.customvisuals.com/code.shtml>. Look
for System Load near the top of that page. You can also see something
pulling data from a URL at <http://www.customvisuals.com/> by viewing
the source of that page. Check the graph on the left side of the page.
