IGNumericAngleAxis Class Reference
IGNumericAngleAxis is a polar axis used by polar series, such as IGPolarScatterSeries. IGNumericAngleAxis is used in conjunction with IGNumericRadiusAxis as part of the requirement for polar series. This axis displays numeric labels in a clockwise fashion. The labels can be displayed counter clockwise by setting isInverted to YES.
IGNumericAngleAxis supports linear and logarithmic scales.
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.
