java.lang.Object
- gov.nih.mipav.model.algorithms.ContourPlot.CoordSysScrollZoom

All Implemented Interfaces:

ContourPlot.InteractionConstants, java.awt.event.MouseWheelListener, java.util.EventListener

Enclosing class:

ContourPlot
```
public class ContourPlot.CoordSysScrollZoom
extends java.lang.Object
implements java.awt.event.MouseWheelListener, ContourPlot.InteractionConstants
```
The CoordSysScrollZoom class implements a MouseWheelListener that realize zooming functionality for the coordinate view of the ContourPlot.CoordSysRenderer. When registering this with an ContourPlot.JPlotterCanvas and corresponding ContourPlot.CoordSysRenderer turning the scroll wheel zooms into or out of the current coordinate system view. The zoom factor can be set and is by default 2.0.
Intended use: CoordSysScrollZoom zoom = new CoordSysScrollZoom(canvas, coordsys).register();

    Specified by:
    
    mouseWheelMoved in interface java.awt.event.MouseWheelListener
  - setZoomFactor
```
public ContourPlot.CoordSysScrollZoom setZoomFactor(double zoomFactor)
```
    Sets the zoom factor of this ContourPlot.CoordSysScrollZoom. The default value is 2.0. Using a value in ]0,1[ will reverse the zoom direction.
    
    Parameters:
    
    zoomFactor - to be set
    
    Returns:
    
    this for chaining
  - getZoomFactor
```
public double getZoomFactor()
```
  - register
```
public ContourPlot.CoordSysScrollZoom register()
```
    Adds this ContourPlot.CoordSysScrollZoom as MouseWheelListener to the associated canvas.
    
    Returns:
    
    this for chaining
  - setZoomedAxes
```
public ContourPlot.CoordSysScrollZoom setZoomedAxes(int axes)
```
    Sets the axes to which this scroll zoom is applied. Default are both x and y axis.
    
    Parameters:
    
    axes - ContourPlot.InteractionConstants.X_AXIS, ContourPlot.InteractionConstants.Y_AXIS or X_AXIS|Y_AXIS
    
    Returns:
    
    this for chaining
  - getZoomedAxes
```
public int getZoomedAxes()
```
    Returns:
    
    the axes this scroll zoom applies to, i.e. ContourPlot.InteractionConstants.X_AXIS, ContourPlot.InteractionConstants.Y_AXIS or X_AXIS|Y_AXIS
  - deRegister
```
public ContourPlot.CoordSysScrollZoom deRegister()
```
    Removes this ContourPlot.CoordSysScrollZoom from the associated canvas' mouse wheel listeners.
    
    Returns:
    
    this for chaining
