All Implemented Interfaces:

MouseListener, MouseMotionListener, ImageObserver, MenuContainer, Serializable, Cloneable, EventListener, Accessible

public class PlotCanvas
extends ImageCanvas

This subclass of ImageCanvas has special provisions for plots: - Zooming: sets the plot range - Scrolling: moves data area This behavior is suppressed if the plot is frozen

Constructor Summary

Constructors

Constructor	Description

Method Summary

Modifier and Type	Method	Description
void	fitToWindow()	Resizes the plot (unless frozen) to fit the window
Plot	getPlot()	Returns the Plot displayed in this canvas
boolean	isFrozen()	Whether the plot is frozen, i.e.
void	mouseExited(MouseEvent e)	overrides ImageCanvas.mouseExited; removes 'range' arrows
void	mousePressed(MouseEvent e)	overrides ImageCanvas.mousePressed: no further processing of clicks on 'range' arrows
void	mouseReleased(MouseEvent e)	Overrides ImageCanvas.mouseReleased, handles clicks on 'range' arrows
protected void	scroll(int sx, int sy)	overrides ImageCanvas.scroll; if plot is not frozen, scrolling modifies the plot data range
void	setMagnification(double magnification)	The image of a PlotCanvas is always shown at 100% magnification unless the plot is frozen
void	setPlot(Plot plot)	Tells the PlotCanvas which plot to use for zooming etc.
void	setSourceRect(Rectangle r)	Scrolling a PlotCanvas is updating the plot, not viewing part of the plot, unless the plot is frozen
protected void	setupScroll(int ox, int oy)	overrides ImageCanvas.setupScroll; if plot is not frozen, scrolling modifies the plot data range
void	unzoom()	Implements the Image/Zoom/Original Scale command.
void	zoom(String arg)	Zoom operations that are handled by ij.plugin.Zoom
void	zoom100Percent()	Implements the Image/Zoom/View 100% command: Sets the original frame size as specified in Edit/Options/Plots (unless the plot is frozen)
void	zoomIn(int sx, int sy)	Zooms in by modifying the plot range; sx and sy are screen coordinates
void	zoomOut(int sx, int sy)	Zooms out by modifying the plot range; sx and sy are screen coordinates
