Hello, Columns of the table which I use for creating charts is like following: resource_id, kpi_0, kpi_1, kpi_2. I want to use kpi_0, kpi_1, and kpi_2 for values and since these columns only contain integer values I need to specifiy the corresponding categories by hand. In short, I need to write category expression something like: ["total calls","answered calls","not answered calls"] and value expression like: [$F{kpi_0},$F{kpi_1},$F{kpi_2}]. How can I do that. Any help (including DB tricks) will be appreciated. Thank you.
