Forum OpenACS Q&A: Graphs and Charts in OpenACS
Right now we are trying to decide what graphing package to use and to understand how graphing is currently done in the toolkit.
I know Nima and Gustof have worked on this recently but I'm having trouble remembering and finding all the details.
We will try to create a wiki page so that we can get this information in one place rather then spread around threads and chats.
My guess is the Diagram package page the right place to do this. Is this what most people are currently using?
If anyone is currently working on charts and graphs it would appreciate an update either in this thread or on the wiki page.
In the past we've had good results with FusionCharts http://www.infosoftglobal.com/FusionCharts/ . Its not open source (although there is a free Lite version) but its relatively cheap and works well. It uses an XML data feed and displays the results using Flash in the client browser in a variety of configurable formats.
We have experience with this one as it is used on one of our internal projects.
Sufficient for simple graphing.
Lightweight and Easy enough to use.
Documentation is only adequate. Does not seem to have scatter plot support which we need.
Very well documented
There is an example of redrawing a chart dynamically after changing values of
not sure if scatter plots are supported
the graphs don't seem to be as nice as the ones produced by tschartlib above and plotkit below
the graphs really look nice, almost like real graphics ,
has support for scatter plots via minor modification as stated
relies on another ajax framework
no experience with using this package yet.
I used reportlab once and it is opensource http://www.reportlab.org/
It use python.
