+# MPAndroidChart项目使用
+
+开源地址：[https://github.com/open-android/MPAndroidChart](https://github.com/open-android/MPAndroidChart "https://github.com/open-android/MPAndroidChart")
+
+# 运行效果
+
+详细效果请参考MPChartExample例子

+
+## 使用步骤
+
+### 1. 在project的build.gradle添加如下代码(如下图)
+
+	allprojects {
+	    repositories {
+	        maven { url "https://jitpack.io" }
+	    }
+	}
+
+![](screenshots/build.gradle.png)
+
+### 2. 在Module的build.gradle添加依赖
+
+    compile 'com.github.open-android:MPAndroidChart:v3.0.1'
+
+
+### 3.清单文件添加权限
+
+   	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
+
+### 4.布局文件使用
+
+ 	<com.github.mikephil.charting.charts.LineChart
+        android:id="@+id/line_chart"
+        android:layout_width="match_parent"
+        android:layout_height="match_parent"/>
+
+### 5.Activity中初始化
+
+    mChart = (LineChart) findViewById(R.id.line_chart);//初始化对应的Chart控件
+	//省略部分代码，具体请参考MPChartExample例子实现想要的效果
+    setData(1000, 500f);//给图表设置数据
+    mChart.invalidate();//刷新
+
+	
+
+* 详细的使用方法在DEMO里面都演示啦,如果你觉得这个库还不错,请赏我一颗star吧~~~
