單個圖表
window.onresize = myChart.resize;
1
可以完成自適應，就是把window的onresize事件賦值爲echart的resize事件。
2. 多個圖表（也可用於單個圖表）
window.onresize = function () {
myChart.resize();
myChart1.resize();
}
window.addEventListener("resize", () => {
this.myChart.resize();
this.myChart1.resize();
});
例子如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<!-- 爲ECharts準備一個具備大小（寬高）的Dom -->
<div id="main" style="width: 100%;height:400px;"></div>
<div id="main1" style="width: 100%;height:400px;"></div>
</body>
<script src="../frames/ECharts/echarts.js"></script>
<script type="text/javascript">
// 基於準備好的dom，初始化echarts實例
var myChart = echarts.init(document.getElementById('main'));
// 指定圖表的配置項和數據
var option = {
title: {
text: 'ECharts 入門示例'
},
tooltip: {},
legend: {
data:['銷量']
},
xAxis: {
data: ["襯衫","羊毛衫","雪紡衫","褲子","高跟鞋","襪子"]
},
yAxis: {},
series: [{
name: '銷量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
};
// 使用剛指定的配置項和數據顯示圖表。
myChart.setOption(option);
var myChart1 = echarts.init(document.getElementById('main1'));
var option1 = {
title: {
text: 'ECharts 入門示例'
},
tooltip: {},
legend: {
data:['銷量']
},
xAxis: {
data: ["襯衫","羊毛衫","雪紡衫","褲子","高跟鞋","襪子"]
},
yAxis: {},
series: [{
name: '銷量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
};
// 使用剛指定的配置項和數據顯示圖表。
myChart1.setOption(option1);
//window.onresize = myChart.resize; //單個圖表
// 下面兩種可用於多個圖表和單個圖表
window.onresize = function () {
myChart.resize();
myChart1.resize();
}
//window.addEventListener("resize", () => {
//this.myChart.resize();
//this.myChart1.resize();
//});
