react中使用echarts（人物关系图）

项目中有时会用到echarts，可能不同的框架中语法稍有变通，前几天在react项目中遇到，写此篇以作记录。

不同的charts语法跟支持不同，本篇"echarts": "^4.2.0-rc.2"

前期准备

cnpm i -S echarts

import echarts from 'echarts/lib/echarts';    //必须
import "echarts/lib/chart/graph";           //引入折线图（按需）
import'echarts/lib/chart/line’              //引入折线图（按需）

App.jsx

import echarts from 'echarts/lib/echarts';
import "echarts/lib/chart/graph";
import options from './options';    //echarts相关配置

componentDidMount(){
    let myChart = echarts.init(document.getElementById('main'));
    //若有数据交互此处改变渲染数据，保留原有样式与配置
    if(res.data.nodes){     
        options.series[0].data=res.data.nodes;
        options.series[0].links=res.data.links;
    }
    // 绘制图表
    myChart.setOption(options);
    //一些事件
    myChart.on('click', params=> {
        ...
        console.log(params.data);
    });
}

render() {
    return (
        <div className='atlas-wrap'>
            <div id="main"></div>      //可通过id设置样式
        </div>
    )
}

options.js
