Hello, I'm trying to utilize ZGDChart to make some graphs of data from a PostgreSQL database. The website users go through 1 to 3 pages of forms to specific what data they want a report on and then the numbers are generated in the final action DTML method. I really want to have a graph on that page and so far have found ZGDChart as a tool. Unfortunately it looks to me like none of the data methods work for my situation: DTML-method : the method in the chart needs to receive variables to get the data, I can't find a way to pump them in Tiny Table: If I could insert data into a TinyTable with my final method action it would work, But that doesn't appear to be how TinyTable works ZSQL Query: need to pass variables into the query. It's not a vanilla lookup but a calculation too. Python Script: Can't say I know enough about python to try, but it looks like I'd run into the same variable problems. Any suggestions? Any other products out there for generating graphs in Zope? thanks, Scott
