我要评论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 () => {
window.onresize = null;
loopref?.current?.clearloop();
loopref.current = null;
};
}, [chartid, options]);
usedebounceeffect(() => {
let mychart;
let chartdom;
if (chartref) {
chartdom = chartref.current;
mychart = echarts.init(chartdom);
options && mychart.setoption(options);
mychart.resize();
}
window.onresize = () => {
mychart.resize();
};
}, [size], {
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 = [122,112,233,123,122,788,900];
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。
color: '#b1b6c2',
fontstyle: 'normal',
fontweight: 'normal',
fontfamily: 'sans-serif',
fontsize: 14,
},
formatter: record => {
let result = `${record.name}：${record.value} 次`;
return result;
},
},
xaxis: {
type: 'value',
boundarygap: [0, 0.01],
splitline: {
show: false,
},
},
yaxis: {
type: 'category',
data: yaxisdata,
scale: true,
axistick: {
// x轴刻度线
show: false,
alignwithlabel: true,
},
axislabel: {
interval: 0,
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
itemstyle: {
normal: {
// 柱状图上显示数量
label: {
show: true, // 是否显示
position: [220, 0], // 位置
formatter: '{@value}' + '次', // 内容
color: '#a5adba', // 文字颜色
},
color: '#2275f0', // 柱子颜色
},
},
data: echardata,
},
],
};
return (
<div style={{height:300, width: 400}}>
<commonchart options={chartoptions} />
</div>
);
};
