React使用Echarts

1.React專案安裝匯入Echarts

$ npm install echarts --save

2.元件頁面中使用Echarts

// 匯入echarts 並將全部匯入的命名為echarts
import * as echarts from 'echarts'
import { useEffect, useRef } from 'react'
 
const Home = () => {
  const domRef = useRef()
 
  useEffect(() => {
    chartTnit()
  }, [])
 
  const chartTnit = () => {
    // 基於準備好的dom，初始化echarts範例
    const myChart = echarts.init(domRef.current)
 
    // 繪製圖表
    myChart.setOption({
      title: {
        text: 'ECharts 入門範例'
      },
      tooltip: {},
      xAxis: {
        data: ['襯衫', '羊毛衫', '雪紡衫', '褲子', '高跟鞋', '襪子']
      },
      yAxis: {},
      series: [
        {
          name: '銷量',
          type: 'bar',
          data: [5, 20, 36, 10, 10, 20]
        }
      ]
    })
  }
 
  return (<div>
    {/* 掛載節點 */}
    <div ref={domRef} style={{ width: '500px', height: '500px' }}></div>
  </div>)
}
export default Home

React使用Ant-design-charts

1.React專案安裝匯入Ant-design-charts

$ npm install @ant-design/charts --save

2.元件頁面中使用Ant-design-charts

 import React from 'react'
// 引入Column柱狀圖表
import { Column } from '@ant-design/charts'
 
const Home = () => {
 
  const data = [
    { type: '傢俱家電', sales: 38 },
    { type: '糧油副食', sales: 52 },
    { type: '生鮮水果', sales: 61 },
    { type: '美容洗護', sales: 145 },
    { type: '母嬰用品', sales: 48 },
    { type: '進口食品', sales: 38 },
    { type: '食品飲料', sales: 38 },
    { type: '家庭清潔', sales: 38 },
  ]
  const config = {
    data,
    xField: 'type',
    yField: 'sales',
    label: {
      // 可手動設定 label 資料標籤位置
      position: 'middle',
      // 'top', 'bottom', 'middle',
      // 設定樣式
      style: {
        fill: '#FFFFFF',
        opacity: 0.6,
      },
    },
    xAxis: {
      label: {
        autoHide: true,
        autoRotate: false,
      },
    },
    meta: {
      type: {
        alias: '類別',
      },
      sales: {
        alias: '銷售額',
      },
    },
  }
  return <div>
    <Column {...config} />
  </div>
}
export default Home

元件封裝（封裝Echarts元件範例）

1.在components下新建元件

這裡名字為Bar，目錄結構如下：

2. components/Bar/index.js

// Bar元件  子元件
import * as echarts from 'echarts'
import { useEffect, useRef } from 'react'
 
// 將用來自定義的提取出來
const Bar = ({ title, xData, yData, style }) => {
  const domRef = useRef()
 
  useEffect(() => {
    chartTnit()
  }, [])
 
  const chartTnit = () => {
    // 基於準備好的dom，初始化echarts範例
    const myChart = echarts.init(domRef.current)
 
    // 繪製圖表
    myChart.setOption({
      title: {
        text: title
      },
      tooltip: {},
      xAxis: {
        data: xData
      },
      yAxis: {},
      series: [
        {
          name: '銷量',
          type: 'bar',
          data: yData
        }
      ]
    })
  }
 
  return (<div>
    {/* 掛載節點 */}
    <div ref={domRef} style={style}></div>
  </div>)
}
export default Bar

3.Home/index.js

//Home元件  父元件
import Bar from '@/components/Bar'
 
const Home = () => {
  return (<div>
    {/* 使用Bar元件 */}
    <Bar
      title='ECharts 入門範例111'
      xData={['襯衫', '羊毛衫', '雪紡衫', '褲子', '高跟鞋', '襪子']}
      yData={[5, 20, 36, 10, 10, 20]}
      style={{ width: '500px', height: '500px' }} />
 
    <Bar
      title='ECharts 入門範例222'
      xData={['襯衫', '羊毛衫', '雪紡衫', '褲子', '高跟鞋', '襪子']}
      yData={[5, 20, 36, 10, 10, 20]}
      style={{ width: '500px', height: '500px' }} />
 
  </div>)
}
export default Home
