A calculated field can be written similar to the following for whatever measure is on the label shelf:
if sum([Measure])=0 then 'N/A'
else str(sum([Measure])) end
Since the measure is now a string, it may be necessary to add some additional verbiage in the second half of the calculation to get it to return the desired output.
Hope this helps!
But the major issue here is that the Harvey ***** still appear when the data value is 0,0 (green & red).
Refer to the encirled part of the image above.
How do I not hvae any chart in the area where the data is null?
