利用DateByItemView画条线图

首先，导入DateByItemView框架，框架在例子中稍后会补上。

这个框架使用方便。

代码：

#define SCREEN_WIDTH [[UIScreen mainScreen]bounds].size.width
#define SCREEN_HEIGHT [[UIScreen mainScreen]bounds].size.height

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
    
    NSArray *dateArray = [NSArray arrayWithObjects:@"0时",@"1时", @"2时", @"3时", @"4时", @"5时", @"6时",@"7时",@"8时", @"9时", @"10时", @"11时", @"12时",@"0时",@"1时", @"2时", @"3时", @"4时", @"5时", @"6时",@"7时",@"8时", @"9时", @"10时", @"11时", nil];
    NSArray *ItemArray = [NSArray arrayWithObjects:@"0",@"81", @"2时", @"id", @"4", @"5", @"6",@"7",@"8", @"9", @"10", @"11", @"22时",@"0",@"1", @"2", @"3", @"4", @"5", @"6",@"7",@"8", @"21", @"10", @"12时",@"12时",nil];
    NSArray* dataArray =  @[dateArray,ItemArray];
    DateByItemView *VC = [[DateByItemView alloc]initWithFrame:CGRectMake(0, 20, SCREEN_WIDTH, SCREEN_HEIGHT-100)];
    VC.dataArray = dataArray;
    
    [self.view addSubview:VC];
    
}
