While trying to create a Pie, Column, or Bar chart type in a Dashboard, a user is unable to select the desired report.
Root Cause:
Dashboards that use these Chart Types are only able to pull from reports that use Grouping.
Solution:
Add Grouping to the report. Once this is added, the report can be selected for these Chart Types.
