+
+                  ## Requirements
+
+                  PNChart works on iOS 6.0 and later version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:
+
+                  * Foundation.framework
+                  * UIKit.framework
+                  * CoreGraphics.framework
+                  * QuartzCore.framework
+
+                  You will need LLVM 3.0 or later in order to build PNChart.
+
+
+
+
+                  ## Usage
+
+                  ### Cocoapods
+
+                  [CocoaPods](http://cocoapods.org) is the recommended way to add PNChart to your project.
+
+                  1. Add a pod entry for PNChart to your Podfile `pod 'PNChart', '~> 0.5'`
+                  2. Install the pod(s) by running `pod install`.
+                  3. Include PNChart wherever you need it with `#import "PNChart.h"`.
+
+
+                  ### Copy the PNChart folder to your project

+
+                  //For LineChart
+
+                  lineChart.delegate = self;
+
+
+                  ```
+
+                  ```objective-c
+
+                  //For DelegateMethod
+
+
+                  -(void)userClickedOnLineKeyPoint:(CGPoint)point lineIndex:(NSInteger)lineIndex pointIndex:(NSInteger)pointIndex{
