Interface Zoomable

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 the ChartPanel to control the zooming.

Method Summary

PlotOrientation
getOrientation()
Returns the orientation of the plot.
boolean
isDomainZoomable()
Returns true if the plot's domain is zoomable, and false otherwise.
boolean
isRangeZoomable()
Returns true if the plot's range is zoomable, and false otherwise.
void
zoomDomainAxes(double lowerPercent, double upperPercent, PlotRenderingInfo state, Point2D source)
Zooms in on the domain axes.
void
zoomDomainAxes(double factor, PlotRenderingInfo state, Point2D source)
Multiplies the range on the domain axis/axes by the specified factor.
void
zoomRangeAxes(double lowerPercent, double upperPercent, PlotRenderingInfo state, Point2D source)
Zooms in on the range axes.
void
zoomRangeAxes(double factor, PlotRenderingInfo state, Point2D source)
Multiplies the range on the range axis/axes by the specified factor.
