实现效果:
旋转效果
缩放效果
1、安装echarts
npm install echarts
npm install echarts-gl
2、页面定义容器
<template>
<div class="echarts">
<!-- <div :id="echarts_id" style="width: 400px;height: 400px;"></div> -->
<div id="echarts_id" style="width: 100%;height: 100%;"></div>
</div>
</template>
3、js中引入echarts
import * as echarts from 'echarts'
import 'echarts-gl'
<template> <div class="echarts"> <!-- <div :id="echarts_id" style="width: 400px;height: 400px;"></div> --> <div id="echarts_id" style="width: 100%;height: 100%;"></div> </div> </template> <script lang="js" setup> import { onMounted, watch,ref } from 'vue' import * as echarts from 'echarts' import "echarts-gl" let echarts_id = ref('') const randomCoding = (res) => { var arr = 'abcdefjhijklmnopqrstuvwxyz0123456789' var char = '' for (var i = 0; i < 4; i++) { var num = parseInt(Math.random() * 36) char = char + arr[num] } echarts_id.value = 'echarts_id' + Math.floor(Math.random() * (10000 - 1) + 1) + char // initCharts(echarts_id.value) initCharts('echarts_id') } // 生成扇形的曲面参数方程,用于 series-surface.parametricEquation function getParametricEquation(startRatio, endRatio, isSelected, isHovered, k, height) { // 计算 let midRatio = (startRatio + endRatio) / 2; let startRadian = startRatio * Math.PI * 2; let endRadian = endRatio * Math.PI * 2; let midRadian = midRatio * Math.PI * 2; // 如果只有一个扇形,则不实现选中效果。 if (startRatio === 0 && endRatio === 1) { isSelected = false; } // 通过扇形内径/外径的值,换算出辅助参数 k(默认值 1/3) k = typeof k !== 'undefined' ? k : 1 / 3; // 计算选中效果分别在 x 轴、y 轴方向上的位移(未选中,则位移均为 0) let offsetX = isSelected ?
