public class ChartZoom
extends ChartMouseListener

This class implements a chart zoom class using the Java MouseInputListener interface. The mouse is used to define a zoom rectangle within one or more PhysicalCoordinates objects, and the PhysicalCoordinates objects are re-scaled to match the extents of the zoom rectangle.

Constructor Detail

ChartZoom

public ChartZoom()

The default ChartZoom constructor.

ChartZoom

public ChartZoom(ChartView component,
                 PhysicalCoordinates[] transforms,
                 int numtransforms,
                 boolean brescale)

This constructor creates a new ChartZoom object using the specified component and scales. Since an array of PhysicalCoordinates objects are specified this constructor implements super zooming.

Parameters:

component - A reference to the ChartView object that the chart is placed in.

transforms - An array, size numtransforms, of the PhysicalCoordinates objects associated with the zoom operation.

numtransforms - The number of PhysicalCoordinates objects in the transforms array.

brescale - True designates that the all of the scales should be re-scaled, once the final zoom rectangle is ascertained.

ChartZoom

public ChartZoom(ChartView component,
                 PhysicalCoordinates transform,
                 boolean brescale)

This constructor creates a new ChartZoom object using the specified component and scale. Since only one PhysicalCoordinates object is specified this constructor implements simple zooming.

Parameters:

component - A reference to the ChartView object that the chart is placed in.

transform - The PhysicalCoordinates object associated with the scale being zoomed.

brescale - True designates that the scale should be re-scaled, once the final zoom rectangle is ascertained.

Overrides:

mouseDragged in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent event)

The dummy mouseEntered event method for this object.

Specified by:

mouseEntered in interface java.awt.event.MouseListener

Overrides:

mouseEntered in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

mouseExited

public void mouseExited(java.awt.event.MouseEvent event)

Dummy event listener for this object. In the current implementation mouse messages are only trapped while a mouse button is held down (dragged).

Specified by:

mouseExited in interface java.awt.event.MouseListener

Overrides:

mouseExited in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent event)

The dummy mouseMoved event method for this object.

Specified by:

mouseMoved in interface java.awt.event.MouseMotionListener

Overrides:

mouseMoved in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

mousePressed

public void mousePressed(java.awt.event.MouseEvent event)

The mousePressed event listener for this object. Once the specified mouse button is pressed, the zoom rectangle starts tracking the mouse cursor.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent event)

The mouseReleased event listener for this object. Once the specified mouse button is pressed, then released, the zoom rectangle tracking the mouse cursor disappears.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Overrides:

mouseReleased in class ChartMouseListener

Parameters:

event - The mouse event contains status information about the mouse.

popZoomStack

public int popZoomStack()

Pop a set of zoom coordinate systems from the zoom stack and initialize the current scale with these value, and re-scale the associated axes to match.

Returns:

Returns the current number of levels in the zoom stack.

pushZoomStack

public int pushZoomStack()

Push a set of coordinate systems onto the zoom stack. Handles both simple and super zooming.

Returns:

Returns the current number of scales in the zoom stack.

removeZoomListener

public void removeZoomListener()

This method uninstalls the Zoom object by removing it from the mouse listener list of the ChartView component.

setButtonMask

public void setButtonMask(int buttonmask)

This method specifies what mouse button is trapped as the mouse zoom button.

Overrides:

setButtonMask in class ChartMouseListener

Parameters:

buttonmask - Specifies what mouse button is trapped as the mouse zoom button.

setZoomEnable

public void setZoomEnable(boolean enable)

Once the Zoom object is created and installed using the addMouseMoveListener method, it can be turned on/off using this method.

Parameters:

enable - True turns the mouse listener on.

setZoomRangeLimits

public void setZoomRangeLimits(ChartDimension limits)

This method sets the zoom range limits placed on the zoom operation. Unless explicitly set, these values are set to 1/1000 of the initial x and y scale range.

Parameters:

limits - Sets the zoom range limits.

setZoomRangeLimits

public void setZoomRangeLimits(double x,
                               double y)

This method sets the zoom range limits placed on the zoom operation. Unless explicitly set, these values are set to 1/1000 of the initial x and y scale range.

Parameters:

x - Sets the x-value of the zoom range limits.

y - Sets the y-value of the zoom range limits.

public void setZoomRangeLimitsRatio(ChartDimension ratio)

This method sets the zoom range limits placed on the zoom operation. Unless explicitly set, these values are set to 0.001.

Parameters:

ratio - Sets the zoom range limits.

setZoomStackEnable

public void setZoomStackEnable(boolean on)

Turns on/off the zoom stack.

Parameters:

on - True turns on the zoom stack.

setZoomXEnable

public void setZoomXEnable(boolean bzoomx)

True signifies that the x dimension is affected by the zoom operation.

Parameters:

bzoomx - True signifies that the x dimension is affected by the zoom operation.

setZoomXRoundMode

public void setZoomXRoundMode(int nzoomx)

Sets the zoom rounding mode for x dimension.

Parameters:

nzoomx - Sets the zoom rounding mode for x dimension. Use one of the auto axis rounding constants: AUTOAXES_NEAR, AUTOAXES_FAR, or AUTOAXES_EXACT.

setZoomYEnable

public void setZoomYEnable(boolean bzoomy)

True signifies that the y dimension is affected by the zoom operation.

Parameters:

bzoomy - True signifies that the y dimension is affected by the zoom operation.

setZoomYRoundMode

public void setZoomYRoundMode(int nzoomy)

Sets the zoom rounding mode for y dimension.

Parameters:

nzoomy - Sets the zoom rounding mode for y dimension. Use one of the auto axis rounding constants: AUTOAXES_NEAR, AUTOAXES_FAR, or AUTOAXES_EXACT.
