Interface Zoomable

All Known Implementing Classes:

CategoryPlot, CombinedDomainCategoryPlot, CombinedDomainXYPlot, CombinedRangeCategoryPlot, CombinedRangeXYPlot, FastScatterPlot, PolarPlot, ThermometerPlot, XYPlot

public interface Zoomable

A plot that is zoomable must implement this interface to provide a mechanism for user interface components to control the zooming.

Method Detail

isDomainZoomable

boolean isDomainZoomable()

Returns true if the plot's domain is zoomable, and false otherwise.

Returns:

A boolean.

isRangeZoomable()

isRangeZoomable

boolean isRangeZoomable()

Returns true if the plot's range is zoomable, and false otherwise.

Returns:

A boolean.

isDomainZoomable()

getOrientation

PlotOrientation getOrientation()

Returns the orientation of the plot.

Returns:

The orientation (never null).

zoomDomainAxes

void zoomDomainAxes(double factor,
                    PlotRenderingInfo state,
                    Point2D source)

Multiplies the range on the domain axis/axes by the specified factor. The source point can be used in some cases to identify a subplot, or to determine the center of zooming (refer to the documentation of the implementing class for details).

Parameters:

factor - the zoom factor.

state - the plot state.

source - the source point (in Java2D coordinates).

See Also:

zoomRangeAxes(double, PlotRenderingInfo, Point2D)

zoomDomainAxes

void zoomDomainAxes(double factor,
                    PlotRenderingInfo state,
                    Point2D source,
                    boolean useAnchor)

Multiplies the range on the domain axis/axes by the specified factor. The source point can be used in some cases to identify a subplot, or to determine the center of zooming (refer to the documentation of the implementing class for details).

Parameters:

factor - the zoom factor.

state - the plot state.

source - the source point (in Java2D coordinates).

useAnchor - use source point as zoom anchor?

See Also:

zoomRangeAxes(double, PlotRenderingInfo, Point2D, boolean)

zoomDomainAxes

void zoomDomainAxes(double lowerPercent,
                    double upperPercent,
                    PlotRenderingInfo state,
                    Point2D source)

Zooms in on the domain axes. The source point can be used in some cases to identify a subplot for zooming.

Parameters:

lowerPercent - the new lower bound.

upperPercent - the new upper bound.

state - the plot state.

source - the source point (in Java2D coordinates).

zoomRangeAxes(double, double, PlotRenderingInfo, Point2D)

zoomRangeAxes

void zoomRangeAxes(double factor,
                   PlotRenderingInfo state,
                   Point2D source)

Multiplies the range on the range axis/axes by the specified factor. The source point can be used in some cases to identify a subplot, or to determine the center of zooming (refer to the documentation of the implementing class for details).

Parameters:

factor - the zoom factor.

state - the plot state.

source - the source point (in Java2D coordinates).

zoomDomainAxes(double, PlotRenderingInfo, Point2D)

zoomRangeAxes

void zoomRangeAxes(double factor,
                   PlotRenderingInfo state,
                   Point2D source,
                   boolean useAnchor)

Multiplies the range on the range axis/axes by the specified factor. The source point can be used in some cases to identify a subplot, or to determine the center of zooming (refer to the documentation of the implementing class for details).

Parameters:

factor - the zoom factor.

state - the plot state.

source - the source point (in Java2D coordinates).

useAnchor - use source point as zoom anchor?

zoomRangeAxes

void zoomRangeAxes(double lowerPercent,
                   double upperPercent,
                   PlotRenderingInfo state,
                   Point2D source)

Zooms in on the range axes. The source point can be used in some cases to identify a subplot for zooming.

Parameters:

lowerPercent - the new lower bound.

upperPercent - the new upper bound.

state - the plot state.
