React echarts 组件的封装使用案例
React echarts 组件的封装import React, { useEffect, useRef } from 'react';
import { useSize, useDebounceEffect } from 'ahooks';
import LoopShowTooltip from './echartsTooltipLoop';
import * as echarts from 'echarts';
const CommonChart = props => {
const { chartId, options, autoTooltip } = props;
const chartRef = useRef();
const size = useSize(chartRef);
const loopRef = useRef();
useEffect(() => {
let chartDom;
let myChart;
if (loopRef.current) {
loopRef.current?.clearLoop();
loopRef.current = null;
}
setTimeout(() => {
if (loopRef.current) {
loopRef.current?.clearLoop();
loopRef.current = null;
}
if (chartRef) {
chartDom = chartRef.current;
myChart = echarts.init(chartDom);
options && myChart.setOption(options);
if (autoTooltip) {
loopRef.current = new LoopShowTooltip(myChart, options, {});
}
}
});
window.onresize = () => {
myChart.resize();
};
return () => {

loopRef.current = null;
};
}, );
useDebounceEffect(() => {

myChart.resize();
}
window.onresize = () => {

};
}, , {
wait: 100,
});
return <div ref={chartRef} style={{ width: '100%', height: '100%' }}></div>;
};
export default CommonChart;使用案例
import React from "react";
import CommonChart from './pages/CommonChart/UI'
const Demo = () => {
let echarData = ;
let yAxisData = ['星期一','星期二','星期三','星期四','星期五','星期六','星期日'];
const chartOptions = {
grid: {
top: '8%',
bottom: '15%',
left: '30%',
right: '16%',
// containLabel: true,
},
tooltip: {
trigger: 'item',
show: true,
backgroundColor: '#3A3F4D',
borderWidth: 0,
textStyle: {
// 提示框浮层的文本样式。

fontStyle: 'normal',
fontWeight: 'normal',
fontFamily: 'sans-serif',
fontSize: 14,
},
formatter: record => {
let result = `${record.name}：${record.value} 次`;
return result;
},
},
xAxis: {
type: 'value',
boundaryGap: ,
splitLine: {
show: false,
},
},
yAxis: {

},
axisLabel: {

width: 80,
overflow: 'truncate',
ellipsis: '...',
align: 'left',
margin: 80,
},
axisLine: {
// 坐标轴
show: false,
},
},
series: [
{
name: '2011',
type: 'bar',
showBackground: true,
backgroundStyle: {
color: '#1A1E28',
},
barWidth: 12, // 柱图宽度

},

},
],
};
