此插件为ucharts的二次封装，旨在简化ucharts的使用过程！

目录结构为：
components/u-charts/u-charts.vue //图表组件文件
components/u-charts/js/chartsUtil.js //为图表初始化和通用函数的二次封装文件
components/u-charts/js/u-charts.js|u-charts.min.js  //此文件为ucharts的原文件，请根据ucharts的版本自行升级。



使用说明：
···
<template>
<view>
	<uCharts :show="canvas" :canvasId="arr[0].id" :chartType="arr[0].chartType" :extraType="arr[0].extraType" :cWidth="cWidth" :cHeight="cHeight" :opts="arr[0].opts" :ref="arr[0].id"/>
</view>
</template>
```

参数说明：
show-显示或隐藏图表
canvasId-画布id
chartType-图表基本类型
exraType-图表扩展类型
opts-图表横轴和纵轴等主要数据
cWidth-图表宽度
cHeight-图表高度
ref-$ref.xxx组件函数引用声明
```
