在数据可视化领域，ECharts 是一个非常受欢迎的工具，它可以帮助我们轻松地将数据转换成图表。而地图图表作为数据可视化的一种形式，能够直观地展示地理分布情况。今天，我们就来学习如何在 ECharts 地图上添加个性化图标，让你的地图图表更具视觉冲击力！
一、准备工作
在开始之前，请确保你已经安装了 ECharts。你可以通过以下命令进行安装：
npm install echarts
或者，如果你使用的是 <script> 标签引入，可以添加以下代码到你的 HTML 文件中：
<script src="https://cdn.jsdelivr.net/npm/echarts/dist/echarts.min.js"></script>
二、创建基本的地图图表
首先，我们需要创建一个基本的地图图表。以下是一个简单的示例：
<div id="main" style="width: 600px;height:400px;"></div>
<script type="text/javascript">
var myChart = echarts.init(document.getElementById('main'));
var option = {
title: {
text: '世界地图'
},
tooltip: {},
visualMap: {
min: -200,
max: 200,
left: 'left',
top: 'bottom',
text: ['高','低'], // 文本，默认为数值文本
calculable: true
},
geo: {
map: 'world',
roam: true,
label: {
emphasis: {
show: false
}
},
itemStyle: {
normal: {
areaColor: '#323c48',
borderColor: '#111'
},
emphasis: {
areaColor: '#2a333d'
}
}
},
series: [
{
name: '数据',
type: 'map',
mapType: 'world',
roam: true,
label: {
normal: {
show: true
},
emphasis: {
show: false
}
},
data: [
{name: '非洲', value: Math.round(Math.random() * 1000)},
{name: '欧洲', value: Math.round(Math.random() * 1000)},
{name: '北美洲', value: Math.round(Math.random() * 1000)},
{name: '南美洲', value: Math.round(Math.random() * 1000)},
{name: '亚洲', value: Math.round(Math.random() * 1000)},
{name: '大洋洲', value: Math.round(Math.random() * 1000)},
{name: '南极洲', value: Math.round(Math.random() * 1000)}
]
}
]
};
myChart.setOption(option);
</script>
三、添加个性化图标
现在我们已经创建了一个基本的地图图表，接下来我们将学习如何添加个性化图标。
准备图标资源：首先，你需要准备一个图标文件。这可以是一个
.png、.jpg或.gif格式的图片。修改
series配置：在series配置中，我们将添加一个新的type为'scatter'的系列，并使用symbol属性来指定我们自定义的图标。
以下是一个示例：
”`javascript series: [
// ... 其他系列配置
{
name: '个性化图标',
type: 'scatter',
coordinateSystem: 'geo',
data: [
{
name: '北京',
value: [116.46, 39.92],
symbol: 'path://M9.8,13.5L9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8,13.5 9.8,13.5C9.8,13.5 9.8
