show chartview with animation.

HOW TO USE:

step one:
pod ‘OWBarChartView’, ‘~> 0.0.1’
or
  download Demo.

step two:
Create a NSDictionary as data, the format of the dictionary is as follows:

NSMutableDictionary *dataDic = [NSMutableDictionary dictionary];

NSArray *first_values = @[@(20),@(15),@(30),@(25),@(40)];
UIColor *firstColor = [UIColor redColor];
NSMutableDictionary *first = [NSMutableDictionary dictionary];
[first setObject:first_values forKey:@"values"];
[first setObject:firstColor forKey:@"color"];

NSArray *second_values = @[@(10),@(30),@(25),@(40),@(60)];
UIColor *secondColor = [UIColor yellowColor];
NSMutableDictionary *second = [NSMutableDictionary dictionary];
[second setObject:second_values forKey:@"values"];
[second setObject:secondColor forKey:@"color"];

NSArray *XArray = @[@"Monday", @"Tuesday", @"Wednesday", @"Thursday", @"Friday"];
NSArray *YArray = @[@(5),@(10),@(15),@(20),@(25),@(30),@(35),@(40),@(45),@(50),@(55),@(60),];
[dataDic setObject:first forKey:@"first"];
[dataDic setObject:second forKey:@"second"];
[dataDic setObject:XArray forKey:@"XArray"];
[dataDic setObject:YArray forKey:@"YArray"];

   (Comment: "XArray", "YArray" are necessary.)

step three:
  Create a OWBarChartView.

_barChart = [[OWBarChartView alloc] initWithDataDictionary:dataDic];
    CGFloat chartHeight = 300.0;
    _barChart.frame = CGRectMake(0, (height - chartHeight)/2, width, chartHeight);
    _barChart.structureType = ChartStructureType_Full;
    _barChart.structureLineWidth = 0.5;
    _barChart.asixWidth = 2.0;
    _barChart.XAsixFont = [UIFont systemFontOfSize:12.0];
    _barChart.YAsixFont = [UIFont systemFontOfSize:12.0];
    [self.view addSubview:_barChart];
