目前我的解决方法如下（使用react hooks）
`const [legendHeight, setLegendHeight] = useState<number>(0);`
`const onChartFinished = useCallback((a: any, instance: EChartsInstance) => {
const legendModel = instance.getModel().getComponent("legend");
const legendView = instance.getViewOfComponentModel(legendModel);
const { height } = legendView.group.getBoundingRect();
setLegendHeight(height);
}, []);`
`return (
<ReactECharts
style={{ height: `${legendHeight + 220}px`, width: "100%" }}
option={option}
onEvents={{
finished: onChartFinished,
}}
/>
);`
