TAndroidEChart

使用百度前端EChart框架封装的Android版本
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

添加依赖:

 -:gradle     
 Step 1:添加maven { url 'https://jitpack.io' } 到project的build.gradle        
 allprojects {   
		repositories {   
			...   
			maven { url 'https://jitpack.io' }   
		}   
	}   

versionNum为最新版本的值 如:1.3.1    
Step 2: 添加compile 'com.github.tikeyc:TAndroidEChart:versionNum'到你app的build.gradle     
dependencies {   
     compile 'com.github.tikeyc:TAndroidEChart:versionNum'    
}          
 -:或者直接下载完整项目,import一个module:tandroidechartlibrary

如何使用:

}
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)      
barChartWebView.refreshEchartsWithOption(getLineAndBarChartOption());
