How to use maps to display data in ECharts
ECharts is a powerful data visualization tool that supports a variety of chart types, including line charts and bar charts , pie chart, etc. Among them, map charts are an important component in ECharts and can be used to display the data distribution in various regions. This article will introduce how to use the map function in ECharts and give detailed code examples.
Before we start, we need to prepare the following files:
- echarts.min.js: The core library file of ECharts.
- china.js: China map data file predefined in ECharts, used to draw China maps.
- Data file: The data file we prepared ourselves, in JSON format, contains data for each region.
First, introduce the necessary files in the HTML file:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>ECharts地圖展示數(shù)據(jù)示例</title>
<script src="echarts.min.js"></script>
<script src="china.js"></script>
</head>
<body>
<div id="map" style="width: 800px; height: 600px;"></div>
</body>
</html>Then, write the code in the JavaScript file:
// 創(chuàng)建地圖實例
var myChart = echarts.init(document.getElementById('map'));
// 設(shè)置地圖參數(shù)
var option = {
title: {
text: '全國各省份數(shù)據(jù)分布',
left: 'center'
},
tooltip: {
trigger: 'item'
},
visualMap: {
min: 0,
max: 1000,
left: 'left',
top: 'bottom',
text: ['高', '低'], // 文本，默認(rèn)為數(shù)值文本
calculable: true,
inRange: {
color: ['#e0ffff', '#006edd']
}
},
series: [
{
name: '數(shù)據(jù)',
type: 'map',
mapType: 'china',
roam: false, // 禁止縮放平移
label: {
normal: {
show: true
},
emphasis: {
show: true
}
},
data: [
{name: '北京', value: 500},
{name: '上海', value: 300},
{name: '廣東', value: 800},
// 這里填充自己的數(shù)據(jù)
]
}
]
};
// 使用剛指定的配置項和數(shù)據(jù)顯示圖表
myChart.setOption(option);In the above code, we first pass echarts.init method to create a map instance and bind it to the specified DOM element. Then, we configure the map's style and data by setting the option parameters. In series, we set the map type to map and specified the map data.
Finally, we use myChart.setOption(option) to apply the configuration item to the map instance to display the map.
It should be noted that we only provide part of the data in the code. You need to fill in the data and adjust related configurations according to your actual situation. At the same time, you can display maps of other regions by modifying the map data in the china.js file.
So far, we have completed the operation of using maps to display data in ECharts. Through careful configuration and data filling, you can achieve richer and more diverse map display effects. I hope this article can be helpful to your study and practice!
