I have a report that aggregates (using Groups and Running Total Fields) data. I have customer name (only of a certain type) and a value for each fiscal year (grouped by Customer). As the fiscal year values are percentages, they are Formula Fields calculated using the Running Total Fields. I don't need/want any other data in the report other than these values which I want to chart. I have a sample that builds variables by concatenating them together and then passing them to the subreport. The variables get passed ok, and I think I have them parsed ok, but when I attempt to run the report, its about 3,000 pages long - one line for every record in the source view (from an Oracle database).

So, how do I get the report to ONLY show data from the shared fields that were passed into the subreport and parsed?

How do I create a chart for each customer with the 4 fiscal year values in them?

I believe you're correct in saying the charting is driven off the data. I have an example that passes "merged" data in a shared variable to a subreport, parses it back using the split(varName, sepChar)[recornumber+1]. While I have some idea what its doing, not enough to figure out if it actually works (though it does in the sample with a much simpler data set).
