<!-- Greeting --> Hey @jihun-ddock! I'm [Dosu](https://dosu.dev), your friendly bot here to help you solve bugs and answer your questions while you wait for a human maintainer. Let's tackle this issue together! <!-- Answer --> The issue you're experiencing with the pie chart in Superset, where only NULL values are displayed and other sections are omitted, might be related to how NULL values are handled in the visualization logic. In Superset, NULL values in pie charts are represented with the name `<NULL>`, and there was a known issue with null labels on pie charts that was addressed in a previous update <sup>[[1]](https://github.com/apache/superset/blob/master/superset-frontend/CHANGELOG.md)</sup>. Given that the problem persists even after using the COALESCE function and adjusting sorting and row limits, it might be worth checking if the issue is related to the specific version of Superset you are using (4.1.1 or 4.1.2). The changelog mentions a fix for null labels, which could be relevant to your situation. To troubleshoot further, consider the following steps: 1. Ensure that your Superset instance is updated to the latest version, as there might be fixes for related issues. 2. Double-check the query and data to ensure that the expected categories are correctly represented and not inadvertently filtered out. 3. Review any custom configurations or settings that might affect the rendering of the pie chart. If the issue persists, it might require a deeper investigation into the specific rendering logic of the pie chart in your Superset setup. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
