npm install echarts
npm install echarts-gl
import * as Echarts from 'echarts'
import 'echarts-gl'
import shanghai from 'shanghai.json'
mounted () {
this.initChart()
},
methods: {
initChart () {
const vue = this
let myChart = Echarts.init(this.$refs.mapChart)
myChart.onresize = myChart.resize
Echarts.registerMap('shanghai', shanghai)
const options = {
series:{
name: 'shanghai',
type: 'map3D',
map: shanghai,
aspectScale: 0.9,
selectedMode: false,
shading: 'realistic'
// 后面添加各个属性OBJ
}
}
myChart.setOption(options)
}
}
添加描边
const itemStyle = {
opacity: 1,
borderWidth: 2,
borderColor: '#01CAF8',
shadowColor: 'red'
}
添加区域图片纹理
const realisticMaterial = {
detailTexture: '/1.png',
textureTiling: 1, // 纹理平铺,1是拉伸,数字表示纹理平铺次数
roughness: 1, // 材质粗糙度,0完全光滑,1完全粗糙
metalness: 0, // 0材质是非金属 ,1金属
roughnessAdjust: 0
}
添加区域鼠标移入效果
const emphasis = {
label: {
show: true,
color: '#FFF',
fontSize: 20
},
itemStyle: {
borderColor: '#41EB26',
borderWidth: 5,
color: '#41EB26'
}
}
添加地级市的标签
const label = {
show: true,
formatter: (params) => {
name = params.data.name
if (params.data.alias) name = params.data.alias
return name
},
textStyle: {
backgroundColor: 'transparent',
color: '#FFF',
fontSize: '20',
padding: 0
}
}
此时效果图
颜色有点暗对,添加光线(intensity:环境光强度,值越大,越亮)
const light = {
main: {
color: '#fff',
intensity: 1,
shadow: false,
shadowQuality: 'high',
alpha: 8,
beta: 80
},
ambient: {
color: '#fff',
intensity: 1
}
}
点击事件(可用)
myChart.off('click')
myChart.on('click', function (params) {
})
很对人遇到myChart.off(‘click’)不生效,是因为,你地图在geo上面的。series这儿就没问题了。
