This request is to enable a color selection to be transparent in dashboard stacked bar charts. What this enables is the summing of multiple SUM or Count terms to render the final value graphically. A normal stacked bar seemingly would achieve this, but if any of the terms are negative, the display does not reflect the correct term summing result. Solution is to create a final term to the function of prescribed minimal amplitude, and that being the only one with a non-transparent color.
This gives considerable expanded functionally to charting in that multiple plus/minus terms can be combined to chart the final summed results.
Thanks for consideration.
