I'm not quite sure what would be causing the exception. Can you post your Chart Visualizer Settings and Query? If you don't want to post it for everyone to see, you can also email me at: andrew DOT nurse AT dotnetnuke DOT com and I'd be happy to help.

The Chart Visualizer is fairly limited in the current version and only creates Bar charts with one Bar produced for each row. If you have specific charting-related features you need, feel free to post them here and I'll log them into our Bug/Feature Tracker for future development.

At the moment, I'm the only developer on this project so I'm a little strapped for time (since this is a part-time volunteer effort ) and this means some components go without major improvements (the Chart Visualizer is one of these). Hopefully, in the new year I'll be able to get some more developers on the team and we can start cranking out the releases a little more often.

If you still need something more powerful than the Chart Visualizer and can't wait for future versions, you can check out the "Reporting Services" Visualizer, which lets you create more detailed reports and display them in the Reports Module. You can get more info on Reporting Services here: http://www.gotreportviewer.com/. Note, you DO NOT need to have a license to SQL Server or SQL Server Reporting Services to use the "Local Mode" Reports, those are handled by your web server. You can design reports in Visual Studio or in the free Visual Web Developer Express tool (with this add-in)

Benito,

Are the DLL files with medium trust enabled available for download?  The link provided in your prior post from years ago is no longer valid.  Otherwise if any one else has working Zedgraph medium trust assemblies I would greatly appreciate it.

Thanks,
Kim
