编写图表 & 传参动态改变图表样式
在需要的路径下创建一个echarts文件夹,在里面编写对应的图表文件:
gaugeChart.js
import React from 'react';
import ReactECharts from 'echarts-for-react';
// 获取传参data
function GaugeChart(data) {
const getOption = () => ({
series: [
{
type: 'gauge',
startAngle: data.data.startAngle,
endAngle: 0,
min: 0,
max: data.data.max,
itemStyle: {
color: data.data.color,
},
progress: {
show: true,
roundCap: true,
width: 22,
},
pointer: {
show: false,
},
axisLine: {
roundCap: true,
lineStyle: {
width: 22,
},
},
axisTick: {
show: false,
},
splitLine: {
show: false,
},
axisLabel: {
show: false,
},
title: {
show: false,
},
detail: {
show: false,
},
data: [
{
value: data.data.current,
},
],
},
],
});
return (
<ReactECharts
option={getOption()}
style={{ height: data.data.height, width: data.data.width }}
/>
);
}
export default GaugeChart;
index.js
import GaugeChart from './echarts/gaugeChart';
export default function Dashboard() {
//传参data
return (
<GaugeChart
data={{
current: listData.topRightData.num,
max: 15000,
startAngle: 180,
color: '#6c5dd3',
height: '300px',
width: '370px',
}}
/>
)
}
