uniapp app中使用柱状图 折线图 圆环图和饼图

实现思路

借助echarts.min.js 搭配l-echart进行配置

废话不多说上代码后自己百度了解配置项的意思就好

下面代码是折线图的 ，柱状图和它一摸一样，只需要把line换成bar就好

<template><l-echart ref="chart"></l-echart>
</template>
<script>
import * as echarts from '@/uni_modules/lime-echart/static/echarts.min.js'
export default {props: {// 以下注释部分是从父组件传递过来的options 这仅仅是一个示例 可以很好的展示ui效果options: {type: Object,default: () => {return null}}},data() {return {chart: null}},mounted() {this.$nextTick(() => {this.initChart()})},watch: {options: {handler(n) {if (n) {this.$nextTick(() => {this.initChart()})}},deep: true}},methods: {initChart() {const {labelX,data1,data2,legends,tipLegends,legendIcon,legendWidth,legendColor,gridLeft,gridRight,axisColor,splitColor,lineColor1,lineColor2,formatterAfterTextArr// labels} = this.optionsconst series = [{type: 'line',name: (legends && legends[0].name) || tipLegends,data: data1,symbolSize: 6,smooth: true,areaStyle: {color: 'rgba(' + (lineColor1 || '60, 127, 252') + ', 0.2)'},lineStyle: {color: 'rgba(' + (lineColor1 || '60, 127, 252') + ', 1)'},itemStyle: {color: 'rgba(' + (lineColor1 || '60, 127, 252') + ', 1)'}}]if (data2) {series.push({type: 'line',name: legends && legends[1].name,data: data2,symbolSize: 6,smooth: true,areaStyle: {color: 'rgba(' + (lineColor2 || '254, 189, 145') + ', 0.2)'},lineStyle: {color: 'rgba(' + (lineColor2 || '254, 189, 145') + ', 1)'},itemStyle: {color: 'rgba(' + (lineColor2 || '254, 189, 145') + ', 1)'}})}this.$refs.chart.init(echarts, (chart) => {this.chart = chartthis.chart.setOption({animation: false,tooltip: {trigger: 'axis',// 使用mousemove时，左右滑动会导致图表消失triggerOn: 'click',formatter:formatterAfterTextArr && formatterAfterTextArr.length > 0? function (params) {// x轴文字var result = params[0].axisValue + '\n'params.forEach(function (item) {/*** marker：图例样式；* seriesName：series中每一项的name；* value：data数据中value字段* formatterAfterTextArr: value之后需要补充的文字，数组格式* seriesIndex: series数据索引，当有多条series数据时，会自动获取当前选中索引*/result += `${item.marker}${item.seriesName}：${item.value}${formatterAfterTextArr[item.seriesIndex]}`})return result}: null},legend: legends && {top: '5%', // 控制 板块控制器的位置right: 'center',data: legends,icon: legendIcon || 'roundRect',itemWidth: legendWidth || 14,itemHeight: 8,itemGap: 24, //设置两个legend之间的间距textStyle: {fontSize: 12,color: legendColor || '#69748A',padding: [3, 0, 0, 0],rich: {}}},grid: {left: gridLeft || '5%',top: legends ?

饼图和柱状图也基本一样 稍微改改就好，很简单。大家可以自己搜索，我这里放的是四个之中相对复杂的，也是摸索了一整子，下面附上效果图，希望能帮到大家。
