Examples of com.positive.charts.util.Size2D

com.positive.charts.util.Size2D
A simple class for representing the dimensions of an object. It would be better to use Dimension2D, but this class is broken on various JDK releases (particularly JDK 1.3.1, refer to bugs 4189446 and 4976448 on the Java bug parade). @author David Gilbert
