大家好，又见面了，我是你们的朋友全栈君。
效果如下
1，安装echarts
npm install echarts --save
2,引入
import echarts from "echarts";
import 'echarts/map/js/china.js' //引入中国地图数据 （*********重中之重）
3，配制option
{
visualMap: { //地图图例
show:true,
left: 26,
bottom: 40,
showLabel:true,
pieces: [ //根据数据大小，各省显示不同颜色
{
gte: 100,
label: ">= 1000",
color: "#1f307b"
},
{
gte: 500,
lt: 999,
label: "500 - 999",
color: "#3c57ce"
},
{
gte: 100,
lt:499,
label: "100 - 499",
color: "#6f83db"
},
{
gte: 10,
lt: 99,
label: "10 - 99",
color: "#9face7"
},
{
lt:10,
label:'<10',
color: "#bcc5ee"
}
]
},
geo: { //中国地图设置
map: "china",
scaleLimit: {
min: 1,
max: 2
},
zoom: 1,
top: 120,
label: {
normal: {
show:true,
fontSize: "14",
color: "rgba(0,0,0,0.7)"
}
},
itemStyle: {
normal: {
borderColor: "rgba(0, 0, 0, 0.2)"
},
emphasis: {
areaColor: "#f2d5ad",
shadowOffsetX: 0,
shadowOffsetY: 0,
borderWidth: 0
}
}
},
series: [
{
name: "突发事件",
type: "map",
geoIndex: 0,
data:[]
}
]
}
Vue地图组件—源码如下（引入调用即可使用）
