Need to remove ‘0’ percentages from Rising star program participant by Ethnicity graph

Good Day All!

We are facing one issue in a Customer created Dashboard Report.

Dashboard is created to show the Rising star program participants by Ethnicity graph. we have used seeded measure and union to get the counts as the rising star program participation is captured in2 DFF fields and looking for cumulative sum of the counts.
Counts are coming to 2 dff fields (development program participant 1 and 2). So we create a report with union and getting the counts and total using seeded measure.

We Need to remove ‘0’ percentages from Rising star program participant by Ethnicity graph.

Any insight on this issue will be helpful.
