Using CR 11, I have a bar chart that stacks 2 values by month. The first value A=yellow (thru the formula) the second value is B=green. This report has 12 subreports with these kind of charts. I have grouped and sorted the records to sort by A first then B so that yelllow is always on top. I also set that up in the chart expert. However, very inconsistently it just switches on some of the charts and I cant seem to make it stack correctly. It puts B/green on top of A/yellow on some. Is this a bug? What else can I check?
