The intermittent dashboard rendering issue is almost certainly caused by a **missing size/lifecycle guard combined with how dashboards mount charts differently than the editor**. Let me walk through the specific problems and fixes. *** ### 1. Use `EchartsChartPlugin` instead of `ChartPlugin` In your `index.ts`, you're extending the base `ChartPlugin`, but all ECharts plugins should extend `EchartsChartPlugin` which sets `parseMethod: 'json-bigint'` for proper data handling [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/types.ts#L178-L192): ```typescript // ❌ Your current code import { t, ChartMetadata, ChartPlugin } from '@superset-ui/core'; export default class EchartsThemeRiverChartPlugin extends ChartPlugin { constructor() { super({ buildQuery, controlPanel, loadChart, metadata, transformProps }); } } // ✅ Change to import { t, Behavior } from '@superset-ui/core'; import { EchartsChartPlugin } from '../types'; export default class EchartsThemeRiverChartPlugin extends EchartsChartPlugin< ThemeRiverFormData, ThemeRiverChartProps > { constructor() { super({ buildQuery, controlPanel, loadChart: () => import('./ThemeRiver'), metadata: { behaviors: [Behavior.InteractiveChart], category: t('Trend'), credits: ['https://echarts.apache.org'], description: t('Displays how multiple categories evolve over time...'), name: t('Theme River'), tags: [t('ECharts'), t('Time'), t('Trend'), t('Stacked')], thumbnail, exampleGallery: [{ url: example1 }], }, transformProps, }); } } ``` When you use `EchartsChartPlugin`, the metadata is passed as a plain object (not a `new ChartMetadata(...)` instance) — the constructor wraps it for you [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/types.ts#L178-L192). *** ### 2. Your `transformProps` is missing dashboard-critical props — this is the main issue Your `transformProps` currently returns only `{ refs, echartOptions, width, height, formData }`. On dashboards, the chart framework passes extra hooks and filter state that your chart needs to at least acknowledge. Compare what other working charts return [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/transformProps.ts#L352-L366) [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Funnel/transformProps.ts#L298-L312): ```typescript export default function transformProps( chartProps: ThemeRiverChartProps, ): ThemeRiverTransformedProps { const refs: Refs = {}; const { width, height, formData, queriesData, hooks, // ← you're not destructuring this filterState, // ← or this emitCrossFilters, datasource, } = chartProps; const { setDataMask = () => {}, onContextMenu } = hooks; // ... your existing data transformation logic ... return { refs, echartOptions, width, height, formData, // Add these for dashboard compatibility: setDataMask, emitCrossFilters, onContextMenu, selectedValues: filterState?.selectedValues || {}, coltypeMapping, groupby: [], labelMap: {}, }; } ``` The `filterState` and `hooks` are provided by the dashboard framework. If `setDataMask` or `onContextMenu` aren't properly passed through, event handlers will silently fail and can cause rendering issues. *** ### 3. Event handlers — what they do and how to add them The `allEventHandlers` utility generates `click` and `contextmenu` event handlers [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/utils/eventHandlers.ts#L147-L179): - **`click`**: Implements **cross-filtering** — clicking a data point in one chart filters other charts on the dashboard - **`contextmenu`**: Enables the **right-click menu** for drill-to-detail and drill-by Your `ThemeRiver.tsx` should use them: ```typescript import { ThemeRiverTransformedProps } from './types'; import Echart from '../components/Echart'; import { allEventHandlers } from '../utils/eventHandlers'; export default function ThemeRiver(props: ThemeRiverTransformedProps) { const { height, width, echartOptions, refs, selectedValues } = props; const eventHandlers = allEventHandlers(props); return ( <Echart refs={refs} height={height} width={width} echartOptions={echartOptions} eventHandlers={eventHandlers} selectedValues={selectedValues} /> ); } ``` For `allEventHandlers` to work, your `transformProps` must return `groupby`, `labelMap`, `selectedValues`, `setDataMask`, `onContextMenu`, `emitCrossFilters`, `coltypeMapping`, and `formData` [[5]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/utils/eventHandlers.ts#L147-L159). Since ThemeRiver doesn't have a natural `groupby` for cross-filtering, passing `groupby: []` effectively disables cross-filter clicks (the click handler becomes a no-op) while still enabling context menus. *** ### 4. Update your types to include the new fields Your `ThemeRiverTransformedProps` type should include the cross-filter and context-menu props: ```typescript import { BaseTransformedProps, ContextMenuTransformedProps, CrossFilterTransformedProps, } from '../types'; export type ThemeRiverTransformedProps = BaseTransformedProps<ThemeRiverFormData> & ContextMenuTransformedProps & CrossFilterTransformedProps; ``` This matches the pattern used by Gauge [[6]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Gauge/transformProps.ts) and Funnel [[7]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/plugin-chart-echarts/src/Funnel/transformProps.ts). *** ### Why this causes the "works in editor but not dashboard" behavior In the **chart editor**, the chart is the primary focus — it mounts with full dimensions and minimal cross-filter plumbing. On **dashboards**, charts are embedded in a grid layout that: 1. Mounts them at potentially different lifecycle stages 2. Passes `hooks` with `setDataMask`, `onContextMenu`, and `filterState` 3. Expects the chart to integrate with the cross-filter system When these props are missing from `transformProps`, the dashboard rendering pipeline can behave unpredictably — sometimes rendering fine, sometimes failing silently depending on timing and what other charts are doing on the dashboard. *** ### Quick checklist | Fix | File | |-----|------| | Use `EchartsChartPlugin` instead of `ChartPlugin` | `index.ts` | | Destructure and return `hooks`, `filterState`, `emitCrossFilters` | `transformProps.ts` | | Add `allEventHandlers` and `selectedValues` | `ThemeRiver.tsx` | | Extend types with `ContextMenuTransformedProps` & `CrossFilterTransformedProps` | `types.ts` | <!-- 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.
