#PNChart
You can also find swift version at here https://github.com/kevinzhow/PNChart-Swift
A simple and beautiful chart lib with animation used in Piner and CoinsMan for iOS
PNChart works on iOS 7.0+ and is compatible with ARC projects. If you need support for iOS 6, use PNChart <= 0.8.1. Note that 0.8.2 supports iOS 8.0+ only, 0.8.3 and newer supports iOS 7.0+.
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.
CocoaPods is the recommended way to add PNChart to your project.
- Add a pod entry for PNChart to your Podfile
pod 'PNChart' - Install the pod(s) by running
pod install. - Include PNChart wherever you need it with

Legend has been added to PNChart for Line and Pie Charts. Legend items position can be stacked or in series.
#import "PNChart.h" //For Line Chart //Add Line Titles for the Legend data01.dataTitle = @"Alpha"; data02.dataTitle = @"Beta Beta Beta Beta"; //Build the legend self.lineChart.legendStyle = PNLegendItemStyleSerial; self.lineChart.legendFontSize = 12.0; UIView *legend = [self.lineChart getLegendWithMaxWidth:320]; //Move legend to the desired position and add to view [legend setFrame:CGRectMake(100, 400, legend.frame.size.width, legend.frame.size.height)]; [self.view addSubview:legend]; //For Pie Chart //Build the legend self.pieChart.legendStyle = PNLegendItemStyleStacked; self.pieChart.legendFontSize = 12.0; UIView *legend = [self.pieChart getLegendWithMaxWidth:200]; //Move legend to the desired position and add to view [legend setFrame:CGRectMake(130, 350, legend.frame.size.width, legend.frame.size.height)]; [self.view addSubview:legend];
Now it's easy to update value in real time
