Create a directory** under `superset-frontend/plugins/plugin-chart-echarts/src/YourChartType/` with this structure [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge): ``` YourChartType/ ├── images/ │ ├── thumbnail.png │ └── example1.jpg ├── index.ts # Plugin class ├── EchartsYourChart.tsx # React component ├── controlPanel.tsx # UI controls ├── transformProps.ts # Data → ECharts options ├── buildQuery.ts # Query construction ├── types.ts # TypeScript interfaces └── constants.ts # Default config ``` **2. Plugin class (`index.ts`)** — registers your chart with Superset [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/index.ts): ```typescript import { t, Behavior } from '@superset-ui/core'; import controlPanel from './controlPanel'; import transformProps from './transformProps'; import buildQuery from './buildQuery'; import thumbnail from './images/thumbnail.png'; import { EchartsChartPlugin } from '../types'; import { EchartsYourChartFormData, EchartsYourChartProps } from './types'; export default class EchartsYourChartPlugin extends EchartsChartPlugin< EchartsYourChartFormData, EchartsYourChartProps > { constructor() { super({ buildQuery, controlPanel, loadChart: () => import('./EchartsYourChart'), metadata: { behaviors: [Behavior.InteractiveChart, Behavior.DrillToDetail], category: t('ECharts'), credits: ['https://echarts.apache.org'], description: t('My custom ECharts chart'), name: t('Your Chart Name'), tags: [t('ECharts'), t('Custom')], thumbnail, }, transformProps, }); } } ``` **3. Build query (`buildQuery.ts`)** — usually simple [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/buildQuery.ts): ```typescript import { buildQueryContext, QueryFormData } from '@superset-ui/core'; export default function buildQuery(formData: QueryFormData) { return buildQueryContext(formData, baseQueryObject => [ { ...baseQueryObject }, ]); } ``` **4. Transform props (`transformProps.ts`)** — this is where you map Superset data into ECharts options [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/transformProps.ts): ```typescript import { EChartsCoreOption } from 'echarts'; import { DataRecord } from '@superset-ui/core'; export default function transformProps(chartProps) { const { width, height, formData, queriesData } = chartProps; const data = (queriesData[0]?.data || []) as DataRecord[]; // Transform your data into ECharts format const echartOptions: EChartsCoreOption = { series: [ { type: 'yourEchartsType', // e.g. 'candlestick', 'parallel', etc. data: data.map(row => ({ // Map Superset data to ECharts data format })), }, ], // Add any other ECharts options (tooltip, legend, xAxis, yAxis, etc.) }; return { formData, width, height, echartOptions, refs: {} }; } ``` **5. React component (`EchartsYourChart.tsx`)** — just a thin wrapper [[5]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/EchartsGauge.tsx): ```typescript import Echart from '../components/Echart'; export default function EchartsYourChart(props) { const { height, width, echartOptions, refs } = props; return ( <Echart refs={refs} height={height} width={width} echartOptions={echartOptions} /> ); } ``` **6. Export from the package** — add to `superset-frontend/plugins/plugin-chart-echarts/src/index.ts` [[6]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/index.ts): ```typescript export { default as EchartsYourChartPlugin } from './YourChartType'; ``` **7. Register in MainPreset** — add to `superset-frontend/src/visualizations/presets/MainPreset.js` [[7]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/visualizations/presets/MainPreset.js#L45-L72): ```javascript import { EchartsYourChartPlugin } from '@superset-ui/plugin-chart-echarts'; // Inside the plugins array: new EchartsYourChartPlugin().configure({ key: 'echarts_your_chart' }), ``` That's it! After these changes, rebuild the frontend (`npm run build` or restart the dev server) and your new chart type will appear in the chart picker. The key insight is that `transformProps` is where the real work happens — you take Superset's query results and construct the ECharts option object exactly as you would from the [ECharts documentation](https://echarts.apache.org/en/option.html). The rest is boilerplate registration and wiring. <!-- 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.
