IGCategoryAngleAxis Class Reference
IGCategoryAngleAxis is a category axis used by radial series, such as IGRadialColumnSeries. IGCategoryAngleAxis is used in conjunction with IGNumericRadiusAxis as part of the requirement for radial series. This axis displays category labels in a clockwise fashion. The labels can be displayed counter clockwise by setting isInverted to YES.
A value that determines the frequency of displayed labels.
@property (nonatomic) CGFloat interval
This property is used to set the frequency of axis labels. A value of 1 will display every label. A value of 2 will display every other label, and so on. When unset, the axis will automatically determine the label frequency.
A value (in degrees) that determines the placement of the first label.
@property (nonatomic) CGFloat startAngleOffset
This property can be used to offset the 0th angle. This doesn’t affect the total number of labels, only the starting point of the labels.
