  Does anyone have experience using this with modules? I can't figure out how to pass it enough data to make a Gantt chart and still have it display the image.

  To clarify a bit, if I try to include it as an image file, I need to send it a lot of information from the template file. This doesn't seem possible. I tried it as a plugin, but that doesn't work because of how jpgraph works. (Which I don't really understand, but they don't have a helpful help forum.) :)
  
  So right now I'm thinking I either need to figure out how to send a lot of information on an image call, or else just have the function get the information again. That's less preferable, obviously, since I already have all the data I need.
  
  And I'm not sure if I'm making any sense, 'cause tree pollen is driving me batty.

  I don't know. JpGraph is PHP-based, using the GD image library to make the images. I don't know how I'd use JS to do this.
  
  I think I've had a bit of an idea. With JpGraph, you can create an image on the server. I think I may do that and then just send the image URL. A bit simpler, I think, though I need to do it carefully so I can figure out where the image is going to end up!

  Hi,
  
  we're using JPGraph in out Project Management Module (currently Beta, will be finished soon). You can download it from www.open-star.org and see how we're using JPGraph.

  I couldn't seem to find the project management module. Is it available for general consumption?
  
  I figured out a way to get this to work, but now I've run into problems with milestones, which is frustrating.

  I have been picking away at this for a while, and I think I've got most of the bugs worked out. Now I just need to implement a way to make it not write the image if nothing's changed in the project. Then I want to see if I can get the image mapping working to where it'll be useful for me.
  
  Here's a screen capture of what I've got so far.

  Rgasch,
  
  I'm finishing up a module that I'd like to use a simple Gantt chart on.
  
  Reading the license for JpGraph, you cannot use it in any commercial form (ie, even an intranet for company data) without paying for the professional version.
  
  I might instead just cobble together an HTML / CSS gantt-like chart rather than use a library that restricts distribution.
  
  Will your module users have to buy professional before using your module?
  
  thanks for any info,
  
  NCM
