Echarts使用dataTool写可自定义横坐标的盒须图（箱线图）

在vue2中的完整盒须图组件代码

可自适应浏览器窗体变化，可自定义横坐标，无需写箱线图数据处理逻辑。dataTool是echarts自带的，无需额外安装，只要引入。

<template><span><div ref="BoxPlotChart" id="box-plot"></div></span>
</template><script>
import dataTool from "echarts/extension/dataTool";export default {name: "BoxplotChart",props: {boxplotData: {type: Object,required: true,},},data() {return {option: {title: {text: "",left: 10, //标题显示的位置},tooltip: {trigger: "item",axisPointer: {type: "cross",},},grid: {left: "10%",right: "10%",bottom: "15%",},xAxis: {data: [],type: "category",boundaryGap: true,nameGap: 30,splitArea: {show: false,},splitLine: {show: false,},},yAxis: {type: "value",name: "",splitArea: {show: true,},},series: [{name: "非异常值",type: "boxplot",data: [],tooltip: {//以下是设置tooltip的显示数据和显示格式formatter: function (param) {return [" " + param.name + ": ","上限: " + param.data[5],"上四分位数: " + param.data[4],"中位数: " + param.data[3],"下四分位数: " + param.data[2],"下限: " + param.data[1],].join("<br/>");},},},{name: "异常值",type: "scatter",data: [],},],},};},mounted() {this.initChart();},watch: {boxplotData: function (newVal, oldVal) {this.initChart();},},methods: {initChart() {//使用echarts的dataTool准备数据let dataTmp = this.$echarts.dataTool.prepareBoxplotData(this.boxplotData.boxData);//设置option//设置非异常值数据this.option.series[0].data = dataTmp.boxData;//设置异常值数据this.option.series[1].data = dataTmp.outliers;//根据传入的boxplotData数据动态设置//设置盒须图标题this.option.title.text = this.boxplotData.title;//设置横坐标this.option.xAxis.data = this.boxplotData.xAxisData;//设置纵坐标this.option.yAxis.name = this.boxplotData.yAxisName;const myChart = this.$echarts.init(this.$refs.BoxPlotChart);// 监听窗体大小变化实现自适应window.addEventListener("resize", function () {myChart.resize();});myChart.setOption(this.option);},},
