+  ### 说明
+  
+  本库目前只支持静态数据图形展示
+  不支持滑动/缩放以及如下相关API
+  
+  1.StaticLabelsFormatter staticLabelsFormatter = 
+    new StaticLabelsFormatter(graphView_01,new String[] {"old", "new"},new String[] {"high", "low"}); 
+    此API问题为原三方库遗留问题，由于代码复杂性和功能耦合性暂无法找到解决办法   
+  2.public class GraphView 内takeSnapshotAndShare 
+    此API与项目功能实现无关是一个分享功能， 因此考虑其价值与困难程度暂不考虑实现此功能   
+  2.public class LineGraphSeries 内 public void setDrawAsPath
+   API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现
+  3.public class LineGraphSeries 内 public void setAnimated(boolean animated)
+    API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现
+  4.public class BarGraphSeries 内  public void setAnimated(boolean animated)
+    API（AccelerateInterpolator）缺失并且未找到替代方案导致此类相关功能无法实现
+  5.public class Viewport 内OverScroller / onScroll 
+    涉及到缺失API（AccelerateInterpolator）API缺失并且未找到替代方案导致此类相关功能无法实现
+  6.public class LineGraphSeries 内 AccelerateInterpolator
+    API缺失并且未找到替代方案导致此类相关功能无法实现
