This has been confirmed as still occurring as recently as June 2025 (thanks @shexiaobin for the screenshot). The likely root cause is that logarithmic scales can't represent zero values (log(0) is undefined), which causes ECharts to drop or misrender stacked bar segments that include zeros. A good fix could involve either: (1) clamping zero values to a small epsilon when log scale is enabled, or (2) showing a clear warning when log scale is used with data containing zeros. The relevant code is likely in the ECharts bar chart plugin in `superset-frontend/plugins/plugin-chart-echarts/src/Bar/`. It would be great to see a PR for this — it's been open for over a year with confirmed reproduction.
