Blair,
I haven't seen any documentation on this either. It looks like you can use the "Report Condition Extension" tab to add a filter to the report where one field on the report table matches one field on the current form. The other options is to use the "Advanced Condition Extension" tab and write an encoded query that will be added to the conditions on the report. You can use a javascript or even a script include to create the encoded query that will be applied to the report when the form loads. I put:
javascript:'priority=' + current.priority;
into the report qualifier field on the advanced tab and it limited the chart I had to only show incidents with the same priority level as the current incident. The up side of the Report Condition Extension is that it seemed to update the chart immediately when the field changed. The Advanced Condition only updated when the form reloaded.
Again, I haven't seen any documentation on how any of that is supposed to work, these are just my observations. I hope that helps.
