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）
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
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
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{
width: 750rpx;
height: 500rpx;
}
.echartPieClass{

所有过程就这些，非常容易上手。
