In Pie Chart There is two Data Ponts which has data as Zero, but the same is not displaying the chart,Even though i Uncheck the Suppress Zero Values Check Box, it is not displaying. Kindly Find The Attached Screen Shot.
I think even if you uncheck Suppress Zero checkbox, the Pie Chart will never show the zero values, simply because there's no value or fraction of pie to show. Instead, use a different kind of chart that will show a data even if its value is zero. See attached..
