HUChart是一个简单的（但是是第一个）ios的绘制半圆圈图（半饼图）表的工具。绘制半圆图表是为了在某些情况下，用一个小空间去完成一个完整的圆图。
相关特性：
- 半圆图表绘制工具就像一个 UIView 的组件. 可以不费一点力气绘制一个定制的半圆图表。
- 支持 iOS 6.1以上的版本
- 支持ARC
用法如下：
// Step 1: Create HUSemiCircleChart object with its desire frame CGRect frame = CGRectMake(25, 30, 250, 300); HUSemiCircleChart *semiCircleChart = [[HUSemiCircleChart alloc] initWithFrame:frame]; // Step 2: Setup data NSMutableArray *data = [NSMutableArray arrayWithObjects: [[HUChartEntry alloc]initWithName:@"Chrome" value:@54.1], [[HUChartEntry alloc]initWithName:@"Firefox" value:@27.2], [[HUChartEntry alloc]initWithName:@"IE" value:@11.7], [[HUChartEntry alloc]initWithName:@"Safari" value:@3.8], [[HUChartEntry alloc]initWithName:@"Others" value:@3.2], nil]; [semiCircleChart setData:data]; // Step 3: Setup color (Optional) // colors maybe not setup, will be generated automatically UIColor * color1 = [UIColor colorWithRed:1.0 green:0.0 blue:0.0 alpha:1.0]; UIColor * color2 = [UIColor colorWithRed:0.0 green:1.0 blue:0.0 alpha:1.0]; UIColor * color3 = [UIColor colorWithRed:0.0 green:0.5 blue:0.0 alpha:1.0]; UIColor * color4 = [UIColor colorWithRed:1.0 green:0.0 blue:1.0 alpha:1.0]; UIColor * color5 = [UIColor colorWithRed:0.0 green:0.0 blue:1.0 alpha:1.0]; NSMutableArray *colors = [NSMutableArray arrayWithObjects: color1, color2, color3, color4, color5, nil]; [semiCircleChart setColors:colors]; // Step 4: Setup Chart Title [semiCircleChart setTitle:@"Browser Shared"]; // Step 5: Determine whether chart element text is shown or not. // SHOW_PORTION_TEXT to show element's name // SHOW_PORTION_VALUE to show element's value // DONT_SHOW_PORTION to show element without any text semiCircleChart.showPortionTextType = SHOW_PORTION_TEXT;
