This class separates data that is stored in its parent class from the presentation of that data. The actual implementation is not crucial, except for the fact that it should be efficient. Perhaps in the future this will be substituted by an interface or an abstract class.

|
void |
paint(java.awt.Graphics g)
Paints all of available data in the parent class, not just the increments. |
protected void |
paintIncremental(java.awt.Graphics g)
Draws into g incremental updates stored in the parent class. |
(package private) void |
replot()
This is the key method that gets called when we need to update the presentation because of an incremental data change. |
void |
setSize(java.awt.Dimension size)
Makes sure pre-calculated information gets reassessed when component is resized. |
void |
update(java.awt.Graphics g)
First time bgImage initialization and double buffering logic here. |
protected int |
xToCoord(int x)
Converts grid measurements to pixel measurements along X-axis. |
protected int |
yToCoord(int y)
Converts grid measurements to pixel measurements along Y-axis. |
