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

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 = PNTwitterColor;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];
