uniapp基于uView的UI组件u-grid-item九宫格实现uCharts秋云可视化图表展示
这里使用uView的u-grid-item九宫格组件去显示图标排列
九宫格可以做成多列，移动设备上可以通过左右滑动进行展示

这里需要注意一下uCharts的组件使用，需要先安装组件插件或者自己去插件社区下载一个插件包，然后放到这个目录下就可以使用了，在页面里面使用标签通过设置type属性值区分图表类别，opts设置图表基本设置属性，chartData设置图表数据。
javascript
<template>
<view class="charts-box">
<qiun-data-charts
type="arcbar"
:opts="opts"
:chartData="chartData"

</view>

<script>
export default {
data() {
return {
chartData: {},
//您可以通过修改 config-ucharts.js 文件中下标为 ['arcbar'] 的节点来配置全局默认参数，如都是默认参数，此处可以不传 opts 。实际应用过程中 opts 只需传入与全局默认参数中不一致的【某一个属性】即可实现同类型的图表显示不同的样式，达到页面简洁的需求。
opts: {
