There are no feature flags or `superset_config.py` settings to enable additional ECharts chart types. Here's why: Superset doesn't directly expose the ECharts library to users. Instead, each chart type is implemented as a dedicated plugin class (extending `EchartsChartPlugin`) that requires custom Superset-specific code [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/types.ts#L178-L192): - A **query builder** (`buildQuery`) to fetch data from your datasource - A **control panel** defining the UI options in the chart editor - A **transform function** (`transformProps`) to convert Superset query results into ECharts options - **Metadata** (category, description, thumbnails) All available ECharts plugins are registered in `MainPreset` at application startup [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/visualizations/presets/MainPreset.js#L45-L72) — currently about 23 chart types including Line, Area, Bar, Step Line, Smooth Line, Scatter, Pie, Funnel, Radar, Gauge, Heatmap, Treemap, Sunburst, Sankey, Waterfall, Gantt, and others [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/index.ts#L19-L46). There is a `CHART_PLUGINS_EXPERIMENTAL` feature flag [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/config.py#L556-L557), but it only controls experimental plugins as a group — it doesn't unlock hidden chart types. **To add a new ECharts chart variant**, you would need to write code: 1. Create a new plugin class extending `EchartsChartPlugin` 2. Implement buildQuery, controlPanel, transformProps, and metadata 3. Export it from the plugin package 4. Register it in `MainPreset` So to directly answer your question: what you see is all that's currently supported out of the box in Superset. Expanding it requires development work rather than configuration. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset).* --- Docs are dead.
