Package smile.plot.swing

Class Base

java.lang.Object

smile.plot.swing.Base

public class Base
extends Object

The coordinate base of Canvas. This support both 2D and 3D device-independent logical space where graphics primitives are specified.

The user need supply the lower and upper bounds for each axis. These bounds usually are extended (a little) internally for better view purpose.
