效果图如下

以上为加载接口所得数据的玫瑰图与折线图
具体步骤如下
1,将插件导入Hbuiler 所需要的项目中(插件地址:秋云 ucharts echarts 高性能跨全端图表组件 - DCloud 插件市场)
![](https://i-blog.csdnimg.cn/direct/519078ddd5c246e4b3b5c0ff8d9bd4b6.png)
2,导入成功是这样的

3,打开Ucharts官方地址(uCharts官网 - 秋云uCharts跨平台图表库) 各种图形应有尽有,如下

4,选择自己需要的图形,这里我用玫瑰图,折线图举例
![](https://i-blog.csdnimg.cn/direct/d449791986ea490783c2263a2f51ab42.png)
选择喜欢的类型点击查看代码 ,支持很多app,小程序,我这里用的UNiapp 原生代码
![](https://i-blog.csdnimg.cn/direct/cff5f1d256be4cbcb89db55e2e3f7a71.png)
5,复制代码到自己项目页面中,调整好css,我的代码如下
a,页面代码
<view class="echartPieClass">
<canvas canvas-id="oCwSurlEYAHlHHJgTshuROhNgUmUHblO" id="oCwSurlEYAHlHHJgTshuROhNgUmUHblO" class="charts" @touchend="tap"/>
</view>
<view class="echartPieClass">
<canvas canvas-id="shSXlKCaGHqXyosxTHYDuRySdVunSfAT" id="shSXlKCaGHqXyosxTHYDuRySdVunSfAT" class="charts" @touchend="tap1"/>
</view>
b,js,css代码

<style scoped>
.charts{

所有过程就这些,非常容易上手。
