TKChartDateTimeCategoryAxis Class Reference
Inherits from | TKChartAxis : NSObject |

Overview
The date time category axis of TKChart.
TKChart uses Categorical axes to plot discontinuous dates as categorical values. The axis is valid only in the context of Cartesian series. It also introduces several important properties:
dateComponent - Defines the time component that is used when creating date categories.
baseline - Contains a value, which defines how the series data should be aligned to. (For example: The TKChartBarSeries might render its bars up and down side depending on wether its value is greater or less than the baseline value.)
offset - Determines a axis value where the axis is crossed with another axis
