Echarts自定义地图和添加图标代码示例
作者：白豆腐大大
这篇文章主要给大家介绍了关于Echarts自定义地图和添加图标的相关资料,项目中经常会遇到需要渲染echarts地图的情况,文中通过代码示例介绍的非常详细,需要的朋友可以参考下
介绍：
由于我司在项目中使用到了Echarts，所以我开了Echarts的相关栏目来分享在使用上的经验。这是本栏目的第一篇文章，需要Echarts相关基础，之后会介绍Echarts的基础，需要的朋友可以关注一下。废话不多说，先看看例子：
先到阿里云的地理小工具获取对应的地图json数据并保存到本地，通过registerMap方法加载。地理小工具
主要代码：
<template>
<!-- 中心地图 -->
<div ref="gemEchart" style="width: 100%; height: 100%" />
</template>
<script>
import * as echarts from 'echarts'
import quanZhouJSON from '@/utils/quanzhou.json' // 地图json
import * as echartsOption from '../echartsOption'
export default {
data: () => ({
myEcharts: null,
myData: []
}),
mounted() {
this.init()
// 适应屏幕大小
window.addEventListener('resize', () => {
if (this.myEcharts && this.myEcharts.resize) {
this.myEcharts.resize()
}
})
// 获取数据
this.getData()
},
methods: {
init() {
this.myEcharts = echarts.init(this.$refs['gemEchart'])
echarts.registerMap('泉州', quanZhouJSON)
const option = {
geo: {
map: '泉州',
label: {
show: true,
// 自定义label
formatter: (params) => {
const find = this.myData.find(
(item) => item.name === params.name
)
if (find) {
return `{name|${find.name}}\n{data|${find.value * 100}%}`
} else {
return `{name|${params.name}}`
}
},
// 富文本
rich: {
name: {
height: 24,
color: 'white',
padding: [-80, 0, 0, 0],
fontSize: 18
},
data: {
height: 24,
color: 'white',
padding: [-40, 0, 0, 0],
fontSize: 18
}
}
},
// 地图区域的样式设置
itemStyle: {
areaColor: 'gray' // 区域颜色
},
top: 10,
bottom: 10,
left: 20,
right: 20
},
series: [
{
type: 'map',
map: '泉州',
// 默认情况下，map series 会自己生成内部专用的 geo 组件。用 geoIndex 指定一个 geo 组件，
// 这样的话，map 和 其他 series（例如散点图）就可以共享一个 geo 组件了。
// 当设定了 geoIndex 后，series-map.map 属性，以及 series-map.itemStyle 等样式配置不再起作用，
// 而是采用 geo 中的相应属性。
geoIndex: 0,
data: []
},
// 用于地图中的图标
{
type: 'scatter',
coordinateSystem: 'geo',
data: echartsOption.icon,
symbol: echartsOption.img,
symbolSize: [50, 50],
symbolOffset: [0, 8]
}
],
visualMap: {
// 设置地图范围值显示的颜色
selectedMode: false, // 不能选择
hoverLink: false, // 取消鼠标移入效果
textStyle: {
color: '#fff'
},
