# 在 uni-app 中使用 Apache ECharts
|
||||
|
||||
本项目是 [Apache ECharts](https://github.com/apache/echarts) 的uni-app版本，支持 [Vue.js](https://vuejs.org/) 2/3，以及使用的示例。
|
||||
|
||||
开发者可以通过熟悉的 ECharts 配置方式，快速开发图表，满足各种可视化需求.
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 方式一: 使用 uni_modules 安装（推荐）
|
||||
|
||||
使用 `uni_modules` 方式安装组件库，可以直接通过插件市场导入，通过右键菜单快速更新组件，不需要引用、注册，直接在页面中使用 `echarts-for-uniapp` 组件。[点击安装 echarts-for-uniapp 组件库](https://ext.dcloud.net.cn/plugin?name=echarts-for-uniapp)
|
||||
|
||||
### 方式二: 使用 npm 安装
|
||||
|
||||
在 `vue-cli` 项目中可以使用 `npm` 安装 `echarts-for-uniapp` 库 ，或者直接在 `HBuilderX` 项目中使用 `npm` 。（不推荐后一种方式）
|
||||
|
||||
```bash
|
||||
npm i uniapp-echarts
|
||||
```
|
||||
|
||||
### 创建图表
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<view class="content">
|
||||
<uni-chart :option="option" />
|
||||
</view>
|
||||
</template>
|
||||
|
||||
<script>
|
||||
export default {
|
||||
data() {
|
||||
return {
|
||||
option: {
|
||||
xAxis: {
|
||||
type: 'category',
|
||||
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
|
||||
},
|
||||
yAxis: {
|
||||
type: 'value'
|
||||
},
|
||||
series: [
|
||||
{
|
||||
data: [120, 200, 150, 80, 70, 110, 130],
|
||||
type: 'bar',
|
||||
showBackground: true,
|
||||
backgroundStyle: {
|
||||
color: 'rgba(180, 180, 180, 0.2)'
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
<style>
|
||||
.content {
|
||||
width: 375px;
|
||||
height: 375px;
|
||||
}
|
||||
</style>
|
||||
|
||||
```
|
||||
|
||||
|
||||
这对于所有 ECharts 图表都是通用的，用户只需要修改上面 `option` 的内容，即可改变图表。`option` 的使用方法参见 [ECharts 配置项文档](https://echarts.apache.org/zh/option.html)。对于不熟悉 ECharts 的用户，可以参见 [5 分钟上手 ECharts](https://echarts.apache.org/zh/tutorial.html#5%20%E5%88%86%E9%92%9F%E4%B8%8A%E6%89%8B%20ECharts) 教程。
|
||||
|
||||
完整的例子请参见 [xbmlz/echarts-for-uniapp](https://github.com/xbmlz/echarts-for-uniapp) 项目。

## FAQ
|
||||
|
||||
### 如何获取图表实例？
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<view class="content">
|
||||
<uni-chart @inited="inited" />
|
||||
</view>
|
||||
</template>
|
||||
|
||||
<script>
|
||||
export default {
|
||||
data() {
|
||||
return {}
|
||||
},
|
||||
methods: {
|
||||
inited(chart) {
|
||||
// do something
|
||||
}
|
||||
}
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
### 如何延迟加载图表？
|
||||
|
||||
参见 [pages/lazyLoad](./pages/lazyLoad/index.vue) 的例子，可以在获取数据后再初始化数据。
|
||||
|
||||
### 如何在一个页面中加载多个图表？
|
||||
|
||||
参见 [pages/multiCharts](./pages/multiCharts/index.vue) 的例子。
|
||||
|
||||
### 如何使用 Tooltip？
|
||||
|
||||
具体使用方法和 ECharts 相同，例子参见 [pages/line](./pages/line/index.vue)
|
||||
|
||||
### 如何保存为图片？
|
||||
|
||||
参见 [pages/saveCanvas](./pages/saveCanvas/index.vue) 的例子。
|
||||
|
||||
### 多主题色
|
||||
|
||||
参见 [pages/themeColor](./pages/themeColor/index.vue) 的例子 。
|
||||
|
||||
### 完整示例
|
||||
|
||||
参见 [pages](./pages)
|
||||
|
||||
### 文件太大怎么办？
|
||||
|
||||
本项目默认提供的 ECharts 文件是最新版本的包含所有组件文件。可以下载不同版本的 [ECharts](https://github.com/apache/echarts/blob/master/dist/) 进行替换。建议调试时使用未压缩版本，发布时使用压缩版本，否则文件会太大无法发布。
|
||||
|
||||
发布时，如果对文件大小要求更高，可以在 [ECharts 在线定制](https://echarts.apache.org/zh/builder.html)网页下载仅包含必要组件的包，并且选择压缩。
|
||||
|
||||
下载的文件放在 `uni_modules/echarts-for-uniapp/static/echarts.min.js`，**注意一定需要重命名为 `echarts.min.js`**。
|
||||
|
||||
此外，还可考虑使用微信小程序的[分包策略](https://developers.weixin.qq.com/miniprogram/dev/framework/subpackages/independent.html)
|
||||
|
||||
|
||||
如有其它问题，也欢迎在 [issue](https://github.com/xbmlz/echarts-for-uniapp/issues) 中反馈，谢谢！

|

# 所以在此提醒一下准备要下载的你，如果你从未使用过 echarts 请不要下载 或 谨慎下载。
|

# 如果你确认要下载，麻烦看完文档。还有请注意插件是让echarts在uniapp能运行，API 配置请自行去官网查阅!

# 如果你不会echarts 但又需要图表，市场上有个很优秀的图表插件 uchart 你可以去使用这款插件，uchart的作者人很好，也热情。

# 每个人都有自己的本职工作，如果你能力强可以自行兼容，如果使用了他人的插件也麻烦尊重他人的成果和劳动时间。谢谢。

|

## 安装
|
||||
- 第一步、在uniapp 插件市场 找到 [百度图表](https://ext.dcloud.net.cn/plugin?id=4899) 导入
|
||||
- 第二步、安装 echarts 或者直接使用插件内的echarts.min文件
|
||||
```cmd
|
||||
pnpm add echarts
|
||||
-or-
|
||||
npm install echarts
|
||||
```
|
||||
|
||||
|
||||
**注意**
|
||||
* 🔔 必须使用hbuilderx 3.4.8-alpha及以上
|
||||
* 🔔 echarts 5.3.0及以上
|
||||
* 🔔 如果是 `cli` 项目需要主动 `import` 插件
|
||||
```js
|
||||
import LEchart from '@/uni_modules/lime-echart/components/l-echart/l-echart.vue';
|
||||
export default {
|
||||
components: {LEchart}
|
||||
}
|
||||
```
|
||||
|
||||
## 代码演示
|
||||
### 基础用法
|
||||
```html
|
||||
<view><l-echart ref="chart" @finished="init"></l-echart></view>
|
||||
```
|
||||
|
||||
```js
|
||||
// 如果你使用插件内提供的echarts.min
|
||||
// 也可以自行去官网下载自定义覆盖
|
||||
// 这种方式仅限于vue2
|
||||
import * as echarts from '@/uni_modules/lime-echart/static/echarts.min'
|
||||
//---or----------------------------------
|
||||
|
||||
// 如果你使用 npm 安装了 echarts --------- 使用以下方式
|
||||
// 引入全量包
|
||||
import * as echarts from 'echarts'
|
||||
//---or----------------------------------
|
||||
|
||||
// 按需引入 开始
|
||||
import * as echarts from 'echarts/core';
|
||||
import {LineChart, BarChart} from 'echarts/charts';
|
||||
import {TitleComponent,TooltipComponent,GridComponent, DatasetComponent, TransformComponent, LegendComponent } from 'echarts/components';
|
||||
// 标签自动布局，全局过渡动画等特性
|
||||
import {LabelLayout,UniversalTransition} from 'echarts/features';
|
||||
// 引入 Canvas 渲染器，注意引入 CanvasRenderer 是必须的一步
|
||||
import {CanvasRenderer} from 'echarts/renderers';
|
||||
|
||||
// 注册必须的组件
|

// 组件能被调用必须是组件的节点已经被渲染到页面上

// 1、在页面mounted里调用，有时候mounted 组件也未必渲染完成
|
||||
mounted() {
|
||||
// init(echarts, theme?:string, opts?:{}, chart => {})
|
||||
// echarts 必填， 非nvue必填，nvue不用填
|
||||
// theme 可选，应用的主题，目前只支持名称，如：'dark'
|
||||
// opts = { // 可选
|
||||
// locale?: string // 从 `5.0.0` 开始支持
|
||||
// }
|
||||
// chart => {} ， callback 必填，返回图表实例
|
||||
this.$refs.chart.init(echarts, chart => {
|
||||
chart.setOption(this.option);
|
||||
});
|
||||
},
|
||||
// 2、或者使用组件的finished事件里调用
|
||||
methods: {
|
||||
init() {
|
||||
this.$refs.chart.init(echarts, chart => {
|
||||
chart.setOption(this.option);
|
||||
});
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 数据更新
|
||||
- 使用 `ref` 可获取`setOption`设置更新
|
||||
|
||||
```js
|
||||
this.$refs.chart.setOption(data)
|
||||
```
|
||||
|
||||
## 图表大小
|
||||
- 在有些场景下，我们希望当容器大小改变时，图表的大小也相应地改变。
|
||||
|
||||
```js
|
||||
// 默认获取容器尺寸
|
||||
this.$refs.chart.resize()
|
||||
// 指定尺寸
|
||||
this.$refs.chart.resize({width: 375, height: 375})
|
||||
```
|
||||
|
||||
|
||||
## 常见问题
|
||||
- 微信小程序 `2d` 只支持 真机调试2.0
|
||||
- 微信开发工具会出现canvas不跟随页面的情况，真机不影响
|
||||
- toolbox 不支持 `saveImage`
|
||||
- echarts 5.3.0 的 lines 不支持 trailLength，故需设置为 `0`
|
||||
- dataZoom H5不要设置 `showDetail`
|
||||
|
||||
|
||||
