uni-app ucharts中饼图与圆环图区别

项目情况：

uni-app的用于移动端H5项目，包使用uni_modules目录存放。

图表引用ucharts中的echarts配置的组件方式

区别1 饼图与圆环图在echarts使用的配置都是pie类型。但是配置raduis使用：

radius: ['40%', '70%']

区别2 组件type指明：type="ring"， type='pie'

<view class="charts-box">

<qiun-data-charts :chartData="chartDataPie" :echartsH5="true" :echartsApp="true"

background="none" :eopts="eopts" />

</view>

<u-gap height="30" bg-color="#bfc"></u-gap>

<view class="charts-box">

<qiun-data-charts type="ring" :chartData="Ring2" :echartsH5="true" :echartsApp="true"

background="none" :eopts="eopts2"/>

</view>
