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.

 Hello,

 I'm wondering what people are using for efficiently generating charts and
 graphs on the fly from within a mod_perl environment.  I've been using
 GD::Graph for a while but I'm hoping to get a bit more feature-deep.  I'm
 not
 terribly concerned about getting a bit more complicated if it means better
 efficiency and/or better control, etc.

 Any suggestions?

Just to add to the mess, I use a Java package called KavaChart from Visual

http://www.customvisuals.com/.
