Base

java.lang.Object
- smile.plot.swing.Base

```
public class Base
extends java.lang.Object
```
The coordinate base of PlotCanvas. 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.
