Issue Summary

The Pie Chart Gadget is displaying the wrong number of hits on its Chart results, even though the Filter associated with it correctly displays its results.

The problem seems to happen when you have an automation rule that updates the Field which is used to display the Chart values.

Like in the example below, the "Team" Field is used to display the Chart division, and although all issues in the Filter results are being returned for the same "Team", it displays also a "None" value for the "Team" Field.

Steps to Reproduce

• Create a Filter that would return a single hit for the Gadget Chart
• Add an automation rule for the Field which is used for the Gadget Chart value

Expected Results

The Pie Chart Gadget should display only what's actually returned on its Filter results.

Actual Results

The Pie Chart Gadget actually displays the results, plus the "None" value as displayed in the screenshot above.

Workaround

It's possible to get the correct results if we're working with a free third-party plugin in the gadget: Reports - Charts and Graphs for Jira Dashboard Free.

It will display the results correctly, however, there's a limitation of one chart call per 5 sec, so if you have more than one of these gadgets on the same dashboard, the second gadget will fail to load, but manually refreshing it after 5 secs will work.
