Overview
The category axis of TKChart.
TKChart uses Categorical axes to plot data that contains categorical values. The axis is valid only in the context of Cartesian series. It also introduces several important properties:
majorTickInterval - Defines an interval among major axis ticks
minorTickInterval - Defines an interval among minor axis ticks
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
