Interface crw.data2.AxisCoor

public interface AxisCoor
Interface that needs be implemented by any class that needs to provide a dynamically changing screen position information to the Axis objects. This interface is used as a reference type in the Axis2 class. A possible implementation is: 
	
	class XCoor implements AxisCoor {
			private int[] location;
			public XCoor() {
				location = new int[3];
			}
			public void change() {
				for (int i=0; i

  o 
	getCoordinate(int)
  
  Returns the screen position information for drawing Axis.





  Methods


 o 
getCoordinate

 public abstract int getCoordinate(int indexID)




  
 Returns the screen position information for drawing Axis.
 The class may need to provide position for several different
 axes; thus the int argument  i  is used to separately
 provide different axes locations.  If the axis is an x-axis, then
 location info may be axis's y-coordinate, beginning x, or the
 ending x coordinate. 
 If int[] location  is used to hold the location
 information of several axes, then a possible implementation
 is
 
	public int getCoordinate(int i) {
		if (i < location.length)
			return location[i];
		else 
			return 10;
	}
 



  

    
 Parameters:
    
 indexID - index of the chosen axis.  Application programs
 must make sure that this method returns proper axis coordinates
 for the Axis.
