Class TickMaster

java.lang.Object

org.das2.graph.TickMaster

public class TickMaster
extends java.lang.Object

Class for managing ticks. When a set of plots shares a common column and axis setting, they should all use the same ticks. The other problem this should fix is when a stack of plots all have heights within a couple of pixels of one another, we should try to use the same ticks for them. DasAxis clients should offer their ticks to this master, which will decide which set of ticks to use.
