import React from 'react';
import ReactECharts from 'echarts-for-react'; // or var ReactECharts = require('echarts-for-react');
<ReactECharts
option={this.getOption()}
notMerge={true}

/>Import ECharts.js modules manually to reduce bundle size
With Echarts.js v5:
import React from 'react';
// import the core library.
import ReactEChartsCore from 'echarts-for-react/lib/core';
// Import the echarts core module, which provides the necessary interfaces for using echarts.
import * as echarts from 'echarts/core';
// Import charts, all with Chart suffix
import {
// LineChart,
BarChart,
// PieChart,
// ScatterChart,

// EffectScatterChart,
// LinesChart,
// HeatmapChart,
// PictorialBarChart,
// ThemeRiverChart,
// SunburstChart,
// CustomChart,
} from 'echarts/charts';
// import components, all suffixed with Component
import {
// GridSimpleComponent,
GridComponent,

} from 'echarts/components';
// Import renderer, note that introducing the CanvasRenderer or SVGRenderer is a required step
import {
CanvasRenderer,
// SVGRenderer,
} from 'echarts/renderers';
// Register the required components
echarts.use(
[TitleComponent, TooltipComponent, GridComponent, BarChart, CanvasRenderer]
);
