I hope someone already solved my challenge: I use a group of expressions like Sum(Qty) and Sum(Sales). Now I want to show certain other objects (e.g. credits or reference codes) only if the Sum(Sales) expression is shown in the first object. Does anyone know how to reference which of the grouped expressions is currently used?
If you check 'Show title in chart' in General Tab, and leave textbox below that blank, the expression VALUE will display on the top of the chart, unless you have specified a LABEL for the Expression, then the LABEL for the expression will display at the top of the chart.
Cntrl + Shift + Click and drag will allow you to move that label around.
The way john has explained works like a charm for multiple scenarios. The basic of how you can quickly and easily get the label and also add sorting mechanism to your charts for cyclic expressions is amazing. I have been using this in many of my reports deployed to end users and the functionality just keeps improving in different charts over time for me.
