edu.hws.jcm.draw.Axes
| Axes | | public class Axes extends Drawable (Code) | | A set of horizontal and vertical axes that look OK and
have reasonable, labeled tick marks. The number and spacing of tick
marks changes depending on the scale on the axes. (The heuristics
for computing this could use some improvement.)

| Field Summary | |

|
| BOTTOM | | final public static int BOTTOM(Code) | | A constant that can be used in the setYAxisPosition() method to indicate the placement of the y-axs.
The axis is placed at the bottom of the CoordinateRect.
|
| CENTER | | final public static int CENTER(Code) | | A constant that can be used in the setXAxisPosition() and setYAxisPosition() methods to indicate the placement of the axes.
The axis is placed in the center of the CoordinateRect.

| draw | | public void draw(Graphics g, boolean coordsChanged)(Code) | | Draw the axes. This is not meant to be called directly.
|
| fudge | | double fudge(double x)(Code) | | Translated directly from the Pascal version of xFunctions.
