I had configured some pie chart before. And they can display well. But after I update the version to 7.1.3,the pie chart can’t display well. How to fix this problem thanks.

Hi @blakechang9

The pie chart has gone through a LOT of imrpvoements and breaking changes since pre 7.1.3.

If it’s at all possible, I highly recommend that you upgrade your grafana to Grafana 8 to enjoy the brand new, stable pie chart panel.

If not 8, then I believe 7.5.x will still give considerably more functionality.

I would hate to see you fix your pie charts so they work on 7.1 just to fix them again when you upgrade to a version with the stable pie chart.

You can explore the new pie chart in this dashboard as well:
