PNChart,简洁高效有动画效果的iOS图表库

导入

• pod导入相对简单，要手动导入这个库，先下载下来（https://github.com/kevinzhow/PNChart），解压后把PNChart文件夹拖入工程中

• 运行发现#import"PNRadarChartDataItem.h"报红，在它的.h文件里引 入#import<UIKit/UIKit.h>头文件；#import<UICountingLabel /UICountingLabel.h>报错，下载UICountingLabel（https://github.com/dataxpress/UICountingLabel）解压后把UICountingLabel的.m和.h文件拖入工程，把报错的#import<UICountingLabel/UICountingLabel.h>头文件换为#import"UICountingLabel.h"

项目中引用头文件#import"PNChart.h"

折线图

PNLineChart * lineChart = [[PNLineChartalloc]initWithFrame:CGRectMake(0,135.0,SCREEN_WIDTH,200.0)];  //X轴数据  [lineChart setXLabels:@[@"SEP 1",@"SEP 2",@"SEP 3",@"SEP 4",@"SEP 5"]];    //Y轴数据  NSArray * data01Array =@[@60.1,@160.1,@126.4,@262.2,@186.2];  PNLineChartData *data01 = [PNLineChartDatanew];  data01.color = PNFreshGreen;  data01.itemCount = lineChart.xLabels.count;  data01.getData = ^(NSUInteger index) {      CGFloat yValue = [data01Array[index] floatValue];      return [PNLineChartDataItemdataItemWithY:yValue];  };    //可以添加多条折线  NSArray * data02Array =@[@20.1,@180.1,@26.4,@202.2,@126.2];  PNLineChartData *data02 = [PNLineChartDatanew];  data02.color = PN推terColor;  data02.itemCount = lineChart.xLabels.count;  data02.getData = ^(NSUInteger index) {      CGFloat yValue = [data02Array[index] floatValue];      return [PNLineChartDataItemdataItemWithY:yValue];  };    lineChart.chartData = @[data01, data02];  [lineChart strokeChart];  //加载在视图上  [self.windowaddSubview:lineChart];

柱状图

PNBarChart * barChart = [[PNBarChartalloc]initWithFrame:CGRectMake(0,135.0,SCREEN_WIDTH,200.0)];   //X轴数据  [barChart setXLabels:@[@"SEP 1",@"SEP 2",@"SEP 3",@"SEP 4",@"SEP 5"]];  //Y轴数据  [barChart setYValues:@[@1, @10,@2,@6,@3]];  [barChart strokeChart];    //加载在视图上  [self.windowaddSubview:barChart];

饼状图

PNPieChart *pieChart = [[PNPieChartalloc]initWithFrame:CGRectMake(40.0,155.0,240.0,240.0)items:items];  //饼状图文字颜色  pieChart.descriptionTextColor = [UIColorwhiteColor];  pieChart.descriptionTextFont  = [UIFontfontWithName:@"Avenir-Medium"size:14.0];  //绘制  [pieChart strokeChart];    //加载在视图上  [self.windowaddSubview:pieChart];

圆形进度条

// total参数是进度条的总数据量，current是当前的数据量，closewise是绘制方向，YES是从左到右，NO为从右到左  PNCircleChart *circleChart = [[PNCircleChartalloc]initWithFrame:CGRectMake(40.0,155.0,240.0,240.0)total:@100current:@30clockwise:NO];    //绘制图形  [circleChart strokeChart];    //加载在视图上  [self.windowaddSubview:circleChart];
