Hi all! I have a understanding problem while creating dynamic reports in iReport: I have a chart which can have different Value expressions. My query return lets say 8 values (Turnover, Costs, ...) and i want the user to select in a input controll which values he wants to see. Normally, when i create the chart I have to define: Series expression (required) $F{Shop} for example Category expression (required) $F{CW} for example Value expression (required) $F{Turnover} for example And here i want to place something like: $P{fieldToShop} instead of a fixed field. I now how to work with parameters but I don't konw how to map them to fields. Is it something like: $F{ $P{fieldToShop} } Thanks for your help!
