shit docs, WTF
切换 demo 图表类型
为什么，hover 提示不明显一点呀, 谁TM 知道可以点击呀，modal 好隐蔽！

<!--
极简调用示例，只需指定type及chartData即可。
图表默认配置请修改js_sdk/u-charts/config-ucharts.js对应图表类型下配置
注：1、更新前请自行备份config-ucharts.js、config-echarts.js，以免被覆盖
2、此方式调用组件chartData需自行按图表类型需求的数据格式拼接
配置参数请用在线生成工具(http://demo.ucharts.cn/)生成
3、class="charts-box"这个样式，指定了高度，如果你的父元素有固定高度，请修改为height:100%
