When there is a large number of stacked by values within a bar chart, sometimes the drill-down does not display the correct values.DescriptionWhen there is a large number of stacked by values on a bar chart, the drill down doesn't work properly. Clicking on some of the colored areas does nothing while it is working for other colored areas.Steps to Reproduce It is hard to reproduce it in OOB as you need a lot of data. Basically you need to create a Bar report against a table with a lot of data and use a Stacked by field which will return a lot of Stacked by values. Run the report and notice that clicking on some of the colored areas does nothing while it is working for other colored areas.WorkaroundThere are two possible workarounds: Option 1: Reduce the number of stacked by values (if possible). Option 2: Remove the Stacked by field and create a drill-down report (grouping by the same field that was in the original Stacked by field). Using this method, when the user drills down on a particular Group by, it will display a chart grouping by the original Stacked by field, which is the same information.Related Problem: PRB1371367
