前言
使用百度前度Echart框架：
http://echarts.baidu.com/
https://gitee.com/free/ECharts
参考iOS封装实现：
https://github.com/Pluto-Y/iOS-Echarts
等资料对Android版本的实现进行简单的封装
时间不是很充裕，只能在零碎时间上来一点一点补充，因此肯定会出现许多不足之处
希望在未来的某一天自己能封装的很完善
项目GitHub地址 https://github.com/tikeyc/TAndroidEChart
添加依赖：
- 方式一
Step 1：添加maven { url '[https://jitpack.io](https://jitpack.io/)' } 到project的build.gradle
allprojects {
repositories {
...
maven { url '[https://jitpack.io](https://jitpack.io/)' }
}
}
versionNum为最新版本的值 如：v1.2.1
Step 2: 添加compile 'com.github.tikeyc:TAndroidEChart:versionNum'到你app的build.gradle
dependencies {
compile 'com.github.tikeyc:TAndroidEChart:versionNum'
}
- 方式二
直接下载完整项目，import一个module：tandroidechartlibrary
如何使用：
具体代码：
xml:
<com.tikeyc.tandroidechartlibrary.TEChartWebView
android:id="@+id/barChartWebView"
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.tikeyc.tandroidechartlibrary.TEChartWebView>
可能后续操作需要刷新图表，可以这样调用
（注意：不能在第一时间就用此方法来显示图表，因为第一时间html的标签还未加载完成，不能获取到标签值）
