public class PlotterMessageHandler

extends java.lang.Object

The PlotterMessageHandler provides static methods to handle exceptions and messages generated by plotting classes. In many cases, it is preferable to use these methods to notify the user what went wrong but try to continue without throwing an exception. The current algorithm simply prints to the standard error stream. An single instance of this class is self-maintained and provided to all classes through the Instance() method (this is an example of the Singleton pattern, if you're familiar with that terminology).
