## Requirements

* Xcode 5 or higher

* iOS 5.0 or higher

* ARC

* CoreGraphics.framework



## Demo



Build and run the `JYRadarChartDemo` project in Xcode



##Installation



###CocoaPods




1. Create a Podfile in your project folder if you don't have one

2. Add a pod entry for JYRadarChart to your Podfile `pod 'JYRadarChart'`

3. Install the pod(s) by running `pod install`

4. Include JYRadarChart wherever you need it with `#import "JYRadarChart.h"`



###Manual Install



All you need to do is drop JYRadarChart files into your project, and add `#import "JYRadarChart.h"` to the top of classes that will use it.



##Example Usage



###minimum

	JYRadarChart *p = [[JYRadarChart alloc] initWithFrame:CGRectMake(30, 20, 200, 200)];

    p.dataSeries = @[@[@(51),@(44),@(94),@(84),@(90)]];

    p.attributes = @[@"attack",@"defense",@"speed",@"HP",@"MP"];

	[self.view addSubview:p];



###fully customized



    JYRadarChart *p = [[JYRadarChart alloc] initWithFrame:CGRectMake(20, 20, 200, 200)];



	NSArray *a1 = @[@(81), @(97), @(87), @(60), @(65), @(77)];

	NSArray *a2 = @[@(91), @(87), @(33), @(77), @(78), @(96)];

	

	//set the data series

	p.dataSeries = @[a1, a2];

	

	//how many "circles" in the chart 

	p.steps = 4;

	

	//for the the entire background

	p.backgroundColor = [UIColor whiteColor];

	

	//you can specify the background fill color

	//(just for the chart, not the entire background of the view)

	p.backgroundFillColor = [UIColor grayColor];



	//you can set radius, min and max value by yourself, but if you

	//leave r (will fill the rect), minValue (will be 0), maxValue (default is 100) alone, 

	//that is okay. the points with too big value will be out of the chart and thus invisible

	p.r = 60;

	p.minValue = 20;

	p.maxValue = 120;

	

	//you can choose whether fill area or not (just draw lines) 

	p.fillArea = YES;

    

	//you can specify the opacity, default is 1.0 (opaque)

	p.colorOpacity = 0.7;

	p.attributes = @[@"Attack", @"Defense", @"Speed", @"HP", @"MP", @"IQ"];

	

	//if you do not need a legend, you can safely get rid of setTitles:

	p.showLegend = YES;

	[p setTitles:@[@"archer", @"footman"]];

	

	//there is a color generator in the code, it will generate colors for you

	//so if you do not want to specify the colors yourself, just delete the line below

	[p setColors:@[[UIColor grayColor],[UIColor blackColor]]];

	[self.view addSubview:p];



##Customization



here are all the properties you can change, you can find them in `JYRadarChart.h`



```

@property (nonatomic, assign) CGFloat r;

@property (nonatomic, assign) CGFloat maxValue;

@property (nonatomic, assign) CGFloat minValue;

@property (nonatomic, assign) BOOL drawPoints;

@property (nonatomic, assign) BOOL fillArea;

@property (nonatomic, assign) BOOL showLegend;

@property (nonatomic, assign) BOOL showStepText;

@property (nonatomic, assign) CGFloat colorOpacity;

@property (nonatomic, strong) UIColor *backgroundLineColorRadial;

@property (nonatomic, strong) UIColor *backgroundFillColor;

@property (nonatomic, strong) NSArray *dataSeries;

@property (nonatomic, strong) NSArray *attributes;

@property (nonatomic, assign) NSUInteger steps;

@property (nonatomic, assign) CGPoint centerPoint;



- (void)setTitles:(NSArray *)titles;

- (void)setColors:(NSArray *)colors;

```
