[normalPieChart addAngleValue:0.20 andColor:[UIColor greenColor]];
[normalPieChart addAngleValue:0.30 andColor:[UIColor blueColor]];
[normalPieChart addAngleValue:0.10 andColor:[UIColor orangeColor]];
[self.view addSubview:normalPieChart];###Concentric Pie Chart
SHPieChartView *concentricPieChart = [[SHPieChartView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
concentricPieChart.chartBackgroundColor = UIColorFromRGB(0xFAFAFA);
concentricPieChart.isConcentric = YES;
concentricPieChart.concentricRadius = 70;
concentricPieChart.concentricColor = UIColorFromRGB(0x54525C);
[concentricPieChart addAngleValue:0.40 andColor:[UIColor redColor]];
[self.view addSubview:concentricPieChart];###Half Pie Chart
SHPieChartView *halfChart = [[SHPieChartView alloc] initWithFrame:CGRectMake(10, 400, 100, 100)];
