I've been through the ringer on this one guys.  i'm running dnn version 05.00.01.  I'm running reports version 5.01.00.  I've uploaded both ZedGraph dll files into the bin folder.  I tried both their latest version (5.1.5) and the one in all the instructions that said to use version (5.1.1).  Someone said to use ZedGraph 5.1.1 with reports 5.0.1.  Since i've upgraded the reports module to the latest version, i don't know how to go back.  But i don't know if it would really help either.  Basically in the active visualizer settings there is no option for charts.  There are the following options: Grid, HTML, XSL.  Nothing else.  I've spent many hours trying to get dynamic charts for my customers to view to no avail.  Can anyone tell me what or if I'm doing anything wrong?  Thanks to you all.

Sebastian,

I actually discovered what i wasn't doing.  I didn't know that you have to install an add-in to the module (i had never done that before).  The reports module doesn't have "charts visualizer" installed by default.

About upgrading DNN.  My site is live, it handles invoices and all information for my business.  Do you suspect that any data or functionality would be compromised by upgrading?  Thanks for your help :)
