Constructor Detail

HistCanvas

public HistCanvas(int gd,
                  Frame f,
                  SVar var,
                  SMarker mark)

creates a new histogram canvas

Parameters:

f - frame owning this canvas or null if none

var - source variable

mark - associated marker

Method Detail

getData

public SVar getData(int id)

Description copied from class: PGSCanvas

this method provides an API to fetch data contents of the plot. The id is implementation-dependent, but first two variables x and y should be mapped to 0 and 1 correspondingly. Therefore every plot containting data must support getData(0). For invalid ids null is returned.

Overrides:

getData in class PGSCanvas

updateObjects

public void updateObjects()

Description copied from class: BaseCanvas

rebuilds plot primitives - subclasses should override this method. It is not defined as abstract only for convenience, but minimal subclass simply overrides this method.

Overrides:

updateObjects in class BaseCanvas

paintBack

public void paintBack(PoGraSS g)

Overrides:

paintBack in class BaseCanvas

paintPost

public void paintPost(PoGraSS g)

Overrides:

paintPost in class BaseCanvas

mousePressed

public void mousePressed(MouseEvent ev)

Specified by:

mousePressed in interface MouseListener

Overrides:

mousePressed in class BaseCanvas

mouseMoved

public void mouseMoved(MouseEvent ev)

Specified by:

mouseMoved in interface MouseMotionListener

Overrides:

mouseMoved in class BaseCanvas

mouseReleased

public void mouseReleased(MouseEvent e)

Specified by:

mouseReleased in interface MouseListener

Overrides:

mouseReleased in class BaseCanvas

mouseDragged

public void mouseDragged(MouseEvent e)

Specified by:

mouseDragged in interface MouseMotionListener

Overrides:

mouseDragged in class BaseCanvas

queryObject

public String queryObject(int i)

Overrides:

queryObject in class BaseCanvas

queryPlotSpace

public String queryPlotSpace()

Overrides:

queryPlotSpace in class BaseCanvas

keyPressed

public void keyPressed(KeyEvent e)

Specified by:

keyPressed in interface KeyListener

Overrides:

keyPressed in class BaseCanvas

run

public Object run(Object o,
                  String cmd)

Description copied from class: PGSCanvas

default handing of commands "exportPGS" and "exportPS". Any descendant should call super.run(o,cmd) to retain this functionality

Specified by:

run in interface Commander

Overrides:

run in class BaseCanvas

Parameters:

o - origin of the command

cmd - command string

Returns:

any object, the actual interpretation is up to the calling object

getMouseOverAxis

protected Axis getMouseOverAxis(int x,
                                int y)

getAxisQuery

protected String getAxisQuery(int x,
                              int y)

Overrides:

getAxisQuery in class BaseCanvas

setIsSpine

public void setIsSpine(boolean isSpine)

adjustMargin

public boolean adjustMargin(PoGraSS g)

Description copied from class: BaseCanvas

Possibly adjust mLeft etc.

Overrides:

adjustMargin in class BaseCanvas

Returns:

Returns true if margins have been changed
