Examples of org.jfree.chart.axis.AxisState

org.jfree.chart.axis.AxisState
Instances of this class are used to carry state information for an axis during the drawing process. By retaining this information in a separate object, it is possible for multiple threads to draw the same axis to different output targets (each drawing will maintain separate state information).
