一、echarts中国地图使用案例
1.准备地图数据china.json ; 需要的添加微信：tianma104，我发你
2.引入jquery，引入eachars 库
<script src="http://xx/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://xxx/ajax/libs/echarts/5.0.0-rc.1/echarts.min.js"></script>3.编写js代码
<div id="mapchart" style="width:800px;height:800px;"></div>
<script>
$.ajax({
url: "china.json",
type: "get",
dataType: "json",
success: function (chinaJson) {
echarts.registerMap("china", chinaJson);
mapchar = echarts.init(document.getElementById("mapchart"));
var option = {
title: {
text: "会员分布图",
textStyle: {
fontSize: 15
},
left: "center"
},
tooltip: {
trigger: "item"
},
legend: {
orient: "vertical",
left: "left",
data: ["会员"]
},
visualMap: {
min: 0,
max: 1000,
itemWidth: 10,
itemHeight: 50,
left: "left",
top: "bottom",
text: ["高", "低"], // 文本，默认为数值文本
calculable: true,
// color: ['#5475f5', '#9feaa5'],
inRange: {
color: ['green', 'red'],
},
outOfRange: {
color: ['green']
},
backgroundColor: 'rgba(0,0,0,0.2)',
},
toolbox: {
show: true,
orient: "vertical",
left: "right",
top: "center",
feature: {
dataView: { readOnly: false },
restore: {},
saveAsImage: {}
}
},
pieces: [
{
gt: 0,
color: '#ffd768'
}
],
series: [
{
name: "会员人数",
type: "map",
mapType: "china",
roam: false,
label: {
normal: {
show: true
},
emphasis: {
show: true
}
},
data: []
}
]
};
mapchar.showLoading({
text: "数据加载中，请您耐心等待..."
});
// mapchar.setOption(option);
$.ajax({
url: 'province.json',// 跳转到 action
type: "get",
cache: false,
dataType: "json",
success: function (data) {
if (data != null) {
option.series[0]["data"] = data;
mapchar.setOption(option);
} else {
mapchar.setOption(option);
}
},
error: function (e) {
}, complete: function () {
//不管数据接口成功或异常，都终于载入提示
//停止动画载入提示
mapchar.hideLoading();
}
});
},
error: function (e) {
}, complete: function () {
//不管数据接口成功或异常，都终于载入提示
//停止动画载入提示
mapchar.hideLoading();
}
});
</script>
