```
    Sets the relative viewport location to display the graphic. Can be one of AVKey.NORTHEAST, AVKey.NORTHWEST, AVKey.SOUTHEAST, or AVKey.SOUTHWEST (the default). These indicate the corner of the viewport.
    
    Parameters:
    
    position - the desired graphic position.
  - setProfileLengthFactor
```
public void setProfileLengthFactor(double factor)
```
    Set the profile length factor - has no effect if FOLLOW_NONE or FOLLOW_PATH
    
    Parameters:
    
    factor - the new profile length factor.
  - setResizeBehavior
```
public void setResizeBehavior(java.lang.String resizeBehavior)
```
    Sets the behavior the layer uses to size the graphic when the viewport size changes, typically when the World Wind window is resized. If the value is AVKey.RESIZE_KEEP_FIXED_SIZE, the graphic size is kept to the size specified in its Dimension scaled by the layer's current icon scale. If the value is AVKey.RESIZE_STRETCH, the graphic is resized to have a constant size relative to the current viewport size. If the viewport shrinks the graphic size decreases; if it expands then the graphic enlarges. If the value is AVKey.RESIZE_SHRINK_ONLY (the default), graphic sizing behaves as for AVKey.RESIZE_STRETCH but it will not grow larger than the size specified in its Dimension.
    
    Parameters:
    
    resizeBehavior - the desired resize behavior
  - setSamples
```
public void setSamples(int number)
```

  - setShowPickedLine
```
public void setShowPickedLine(boolean state)

  - setToViewportScale
```
public void setToViewportScale(double toViewportScale)
```
    Sets the scale factor applied to the viewport size to determine the displayed size of the graphic. This scale factor is used only when the layer's resize behavior is AVKey.RESIZE_STRETCH or AVKey.RESIZE_SHRINK_ONLY. The graphic's width is adjusted to occupy the proportion of the viewport's width indicated by this factor. The graphic's height is adjusted to maintain the graphic's Dimension aspect ratio.

    toViewportScale - the graphic to viewport scale factor.
  - setUnit

```
public void setZeroBased(boolean state)
