在 Vue 中让 Echarts 图表自适应可以通过`watch`监听组件的大小变化来实现,具体步骤如下:
1. 安装 echarts 库:
```
npm install echarts --save
```
2. 在 Vue 组件中引入 echarts:
```javascript
import echarts from 'echarts';
```
3. 在 Vue 组件中创建 Echarts 实例:
```javascript
export default {
data() {
return {
chartInstance: null // Echarts 实例
};
},
mounted() {
// 创建 Echarts 实例
this.chartInstance = echarts.init(this.$refs.chart);
// 渲染 Echarts 图表
this.renderChart();
// 监听组件大小变化
this.$nextTick(() => {
window.addEventListener('resize', this.handleResize);
});
},
beforeDestroy() {
// 销毁 Echarts 实例
this.chartInstance.dispose();
// 移除监听事件
window.removeEventListener('resize', this.handleResize);
},
methods: {
renderChart() {
// 渲染 Echarts 图表
this.chartInstance.setOption(...);
},
handleResize() {
// 监听组件大小变化,重新渲染 Echarts 图表
this.chartInstance.resize();
}
}
};
```
4. 在组件模板中定义 Echarts 图表容器:
```html
<template>
<div ref="chart" class="chart-container"></div>
</template>
```
5. 在 CSS 样式中设置 Echarts 图表容器的宽高为 100%:
```css
.chart-container {
width: 100%;
height: 100%;
}
```
这样,当组件大小发生变化时,Echarts 图表就会自动适应容器的大小。
