In VA I have a line chart over time (x-axis) that displays the results of different KPIs (y-axis) according to a selection in a listbox.
All KPIs have "Value" and "Average" and some have a "Target value".
If I add the three roles, then I get a legend item for Target value even if the currently shown KPI doesn't have one (it's missing in the data).
Preferably one would like to choose to display or not display the legend item when data is missing.
Second best would (in my opinion) be to never display the legend item for missing data.
This would, again in my opinion, be needed for all chart objects.
Regards
Andreas
