Forum OpenACS Q&A: What graphing tool to use with OpenACS?

Hi everyone,
I've been looking around for a graphing tool to use with OpenACS.
It needs to be able to draw line charts using data from the database.

So far, I've only found JpGraph, which looks quite good but runs on PHP4.
Read some posts about ino-chart and jplot, which should fit my needs
better, but can't seem to access either one of their websites.

Does anyone have:
1. A copy of jplot or ino-chart?
2. Recommendations of other graphing tools?

Either of the above would be of *great* help! :)

Another option is nsgd, which is available from ftp.aolserver.com/modules/

I used tgdchart when I worked on a project using ACS4 TCL. It's a TCL extension that allows you to draw line charts, pie charts etc via the GDChart C library.

I have acs 3.4 (don't have openacs...yet) and it comes
with a tcl proc that creates bar-charts. look in www/doc
for a file like gra*html (I forget where the proc is but it
starts with 'gr_'). I was just recently playing with
it so I know it works.

It uses html tables and expands 1 pixel images to create the
bars at desired width and length.
