echarts 使用地图，设置背景图片和高亮图片，点击实现高亮显示，更换散点图图片，高亮散点图形，3D悬浮效果展示地图，集成Vue组件

先看下   需要实现的效果：

第一步 需准备需要的插件

 1  注意新版 echarts 的引入方式为：  import * as echarts from 'echarts'，这里我把 echarts 直接挂载到了Vue上，本项目使用echarts比较多，这样的话很方便，也可以在需要echarts的模块按需引入

       在main.js中添加以下代码：

import * as echarts from 'echarts'
Vue.prototype.$echarts = echarts;

2 引入地图数据  ，我这里是下载到本地引用的

import China from '@assets/js/100000';

第二步 需要用到的 知识点 知识点

  1 想要实现3D效果，可以通过设置阴影和边框来搞定，但是发现echarts 给地图设置边框后，会导致所有省的边框都会改变，这不是我们想要的效果，另辟蹊径 ，其实就是把多个地图实例重叠错位显示，实现悬浮3D效果。

2  echarts  image属性 支持 纹理图片，支持base64位图片

代码设置itemStyle：

itemStyle: {

              color: {

                image: piePatternImg,

                repeat: 'repeat'

              },

              areaColor: {

                image: piePatternImg,

                repeat: 'repeat'

              },

              borderColor: '#bddee6',

              borderWidth: 1,

            },

设置选中高亮样式

select: {

              label: {

                show: false,

                color: '#fff'

              },

              itemStyle: {

                areaColor: {

                  image: patternImg,

                  repeat: 'repeat'

                }

              }

            },

设置高亮样式

emphasis: {

              label: {

                show: false,

                color: '#fff'

              },

              itemStyle: {

                areaColor: {

                  image: patternImg,

                  repeat: 'repeat'

                }

              }

            }

单独设置样式：

regions: [

            {

              name: "南海诸岛",

              value: 0,

              itemStyle: {

                normal: {

                  opacity: 0,

                  label: {

                    show: false

                  }

                }

              }

            }

          ],

绑定点击事件 ，选中高亮散点图和底图

myChart.on('click', e => {
        if (!e.data) {
          this.scatterData.map(item => {
            if (item.symbolSize == 30) {
              item.selected = true;
            }
          })
          myChart.setOption(this.option, true);
          return
        }
        // this.$emit('handle-map', this.scatterData[e.dataIndex]);
        this.scatterData.map(item => {
          item.symbol = item.name == e.name ? scatterHImg : scatterImg
          item.label = item.name == e.name ? { backgroundColor: { image: scatterHBg } } : { backgroundColor: { image: scatterBg } };
          item.symbolSize = item.name == e.name ? 30 : 20
          item.selected = item.name == e.name ? true : false;
        })
        myChart.setOption(this.option, true);
      });

下面是代码部分，封装了一个Vue组件，包括给散点图添加点击事件，高亮图标，悬浮显示。文章来源地址https://www.toymoban.com/news/detail-685784.html
