In my report users have to select whether they will to see 1, 2, or 3 years worth of data (there is no default). I have params controlling tablix items as followstwo Boolean parameters: TwoYrs? T/FThreeYrs? T/FHave been able to use the visibility tab of the tablix items to hide them depending on t/f state of the param. More difficult is finding where to control visibility of individual chart lines.chart by default shows data for year(today)-2. But I need refined control to show chart lines of year(today)-1, and year(today)-2 based on the params selected.What I've tried: #1 Created 3 Series groups with filters. eg. YearSeries1 to return only current year data but I don't see where to apply the expression to control the visibility of the Series groups. #2 have created two additional copies of the same chart and added visibility expression to each, but I see two problems. having 3 charts one on top of the other is throwing off the default spacing of the report items and isn't that a lot of overhead?
