34 | * A mediator class to adapt CategoryAxis to {@link HCPlot}. | |
35 | * The problem is that HCPlot needs CategoryAxis-object for both | |
36 | * horizontal and vertical axises with different sets of categories. | |
37 | * However, CategoryAxis only allows single set of categories | |
38 | * to be used per plot, and it is not easy to inherit a subclass | |
39 | * implementing the usage of multiple categories. This mediates the two | |
40 | * classes so that they work nicely together. | |
