Usage

Import header file

#import "EasyCharts.h"

The following describes the basic use of several graphs.

BrokenLineChart

BrokenLineChart now includes :BrokenLineTypeCenterPoint and BrokenLineTypeNormal。

BrokenLineTypeNormalIs an ordinary broken line chart BrokenLineTypeCenterPointmade the selected point always centered

Besides BrokenLineType ，There are two more parameters when creating an object,one is frame, the other is object ECBrokenLineConfig ,parameters below:

You can use ECBrokenLineConfig to configure the attributes of the brokenLine charts，Each attribute is set to default values.Of course you can use nil.

@property (nonatomic, strong) UIColor *brokenLineColor;
@property (nonatomic, strong) UIColor *backVeiwLineColor;
@property (nonatomic, strong) UIColor *backVeiwTextColor;
@property (nonatomic, strong) UIColor *backVeiwBackGroupColor;
@property (nonatomic, strong) UIColor *brokenAbscissaColor;

@property (nonatomic, assign) CGFloat minValue;  //default 0
@property (nonatomic, assign) CGFloat maxValue;  //default 100

@property (nonatomic, assign) CGFloat numberOfIntervalLines; //default 5
@property (nonatomic, assign) BrokenLineType brokenLineType;

Delegate is called when the point on the line is clicked.

- (void)brokenLineView:(ECBrokenLineView *)brokenLineView
   selectedAtIndexPath:(NSIndexPath *)indexPath;

Initialization：

 ECBrokenLineView *brokenLineView = [ECBrokenLineView lineViewWithFrame:frame
                                                      withBrokenLineConfig:nil
                                                            brokenLineType:BrokenLineTypeNormal];
    brokenLineView.delegate = self;
    [self.view addSubview:brokenLineView];

 ECBrokenLineView *brokenLineView = [ECBrokenLineView lineViewWithFrame:frame
                                                      withBrokenLineConfig:nil
                                                            brokenLineType:BrokenLineTypeCenterPoint];
    brokenLineView.delegate = self;
    [self.view addSubview:brokenLineView];

Data filling: ( If the value is less than the minimum value, the minimum value is displayed。If the value is greater than the maximum value, the maximum value is displayed；point on both sides filled with dashed lines)

[self.brokenLineView reloadLineViewDataWithPointValveList:self.pointValveList
                                                    titleText:self.pointTextList];

The effect of BrokenLineTypeNormal	The effect of BrokenLineTypeCenterPoint

ProgressView

Initialization--Just transfer frame.

ECProgressChartView *progressView = [ECProgressChartView progressChartViewWithFrame:frame];
    [self.view addSubview:progressView];

Data filling：

[self.progressView resetProgress:[self createProgress]];

The effect of ProgressView:

BrokenLineChart && ProgressView

Application scene：

PieChart

Initialization--Just transfer frame.

 ECPieChartView *pieView = [ECPieChartView pieChartViewWithFrame:CGRectMake(0, 100, ECScreenW, 200)];
    [self.view addSubview:pieView];

Data filling:Three parameters:percentList、colorList、arcTextList]

[pieView drawPieChartWithPercentList:self.percentList
                               colorList:self.colorList
                             arcTextList:self.arcTextList];

The effect of PieChart:

RadarChartView

Initialization--Just transfer frame.

	ECRadarChartView *rView = [ECRadarChartView radarChartViewWithFrame:CGRectMake(60, 350, 270, 270)];
	[self.view addSubview:rView];

Data filling:

	ECRadarChartConfig *config = [[ECRadarChartConfig alloc] init];
	config.backgroupLineNum = 5;
	config.radius = 100;
	config.drawPointArray = @[@[@(0.5),@(0.4),@(0.5),@(0.1),@(0.9)],
	                              @[@(0.4),@(0.5),@(0.2),@(0.8),@(0.1)],
	                              @[@(0.4),@(0.1),@(0.8),@(0.7),@(0.2)]];
	config.drawLineColorArray = @[[UIColor orangeColor],[UIColor greenColor],[UIColor redColor]];
	config.drawLineTitleArray = @[@"Technology",@"Execution",@"Thinking",@"Endurance",@"Speed"];
	 [rView setupRadarChartConfig:config];

	ECRadarChartConfig *config = [[ECRadarChartConfig alloc] init];
	config.backgroupLineNum = 5;
	config.radius = 100;
	config.drawPointArray = @[@[@(0.5),@(0.4),@(0.5),@(0.1),@(0.9),@(0.4)]];
	config.drawLineColorArray = @[[UIColor orangeColor]];
	config.drawLineTitleArray = @[@"Technology",@"Execution",@"Thinking",@"Endurance",@"Speed",@"Power",];
	 [rView setupRadarChartConfig:config];
