GitHub user dosubot[bot] added a comment to the discussion: ECharts options overrides in themes: How to target specific chart instance
<!-- Answer --> Superset’s theme system only supports ECharts options overrides globally (`echartsOptionsOverrides`) or per chart type (`echartsOptionsOverridesByChartType`). There’s no built-in way to target a specific chart instance (like by slice ID, chart ID, or dashboard context)—overrides always apply uniformly to all charts of a given type, not per instance [ThemeController code](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/theme/ThemeController.tsx) [PR discussion](https://github.com/apache/superset/pull/36389) [Docs](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docs/docs/configuration/theming.mdx). There’s a CSS workaround for visual tweaks: you can use dashboard CSS to target a chart by its chart ID (e.g., `#chart-id-146`) for things like hiding columns in Table charts, but this only affects styling, not ECharts options [CSS example](https://github.com/apache/superset/issues/20453). For advanced or per-instance ECharts customizations, you’d need to modify the frontend code (e.g., chart plugin files like `transformProps.ts`) or build a custom plugin [Discussion](https://github.com/apache/superset/discussions/34256). There’s no evidence of ongoing development or roadmap plans for instance-level ECharts overrides. If you want to explore further or propose a feature, check out the [theming docs](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docs/docs/configuration/theming.mdx) and [related discussions](https://github.com/apache/superset/discussions/34256). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
