<!-- Answer --> This is a known issue with how label positioning is handled for Radar charts in Superset. The label position you select in the UI (like "Inside Left" or "Inside Bottom Right") is passed directly to the ECharts library, which is responsible for rendering the chart. However, ECharts does not currently support all label position options for Radar series as it does for other chart types, so the labels often appear in a default position (typically above the data point) regardless of your selection. There is no additional logic in Superset to adjust or correct this behavior—the setting is forwarded as-is to ECharts without transformation or validation, and there are no recent changes or workarounds documented in Superset for this issue. If precise label positioning is critical, you may want to check the ECharts documentation or issue tracker for updates or consider alternative chart types that offer more robust label placement controls.
