Interface Zoomable

All Known Implementing Classes:
CategoryPlot, CombinedDomainCategoryPlot, CombinedRangeCategoryPlot, CombinedRangeXYPlot, FastScatterPlot, 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, java.awt.geom.Point2D source)
          Zooms in on the domain axes.
 void zoomDomainAxes(double factor, PlotRenderingInfo state, java.awt.geom.Point2D source)
          Multiplies the range on the domain axis/axes by the specified factor.
 void zoomRangeAxes(double lowerPercent, double upperPercent, PlotRenderingInfo state, java.awt.geom.Point2D source)
          Zooms in on the range axes.
 void zoomRangeAxes(double factor, PlotRenderingInfo state, java.awt.geom.Point2D source)
          Multiplies the range on the range axis/axes by the specified factor.
