以下是使用Taro3+Vue3添加图表的步骤:
1. 安装echarts和echarts-taro依赖:
```shell
npm install echarts echarts-taro
```
2. 在需要添加图表的页面中引入echarts和echarts-taro:
```javascript
import * as echarts from 'echarts';
import { ECharts } from 'echarts-taro3-react';
```
3. 在template中添加ECharts组件,并使用ref获取组件实例:
```html
<template>
<view>
<ec-canvas ref="ecCanvasRef" canvas-id="mychart" :ec="ec"></ec-canvas>
</view>
</template>
```
```javascript
setup() {
const ecCanvasRef = ref(null);
const ec = {
onInit: (canvas, width, height) => {
const chart = echarts.init(canvas, null, {
width: width,
height: height
});
ecCanvasRef.value = chart;
return chart;
}
};
return {
ecCanvasRef,
ec
};
}
```
4. 在mounted钩子函数中使用echarts实例绘制图表:
```javascript
mounted() {
const chart = this.ecCanvasRef;
const option = {
// echarts配置项
};
chart.setOption(option);
}
```
