Constructor Detail

LineCanvas

public LineCanvas(int gd,
                  Frame f,
                  SVar xv,
                  SVar[] yvs,
                  SMarker mark)

create a new lineplot

Parameters:

f - associated frame (or null if none)

v1 - variable 1

v2 - variable 2

mark - associated marker

LineCanvas

public LineCanvas(Frame f,
                  SVar xv,
                  SVar[] yvs,
                  SMarker mark)

Method Detail

getXAxis

public Axis getXAxis()

Overrides:

getXAxis in class PGSCanvas

getYAxis

public Axis getYAxis()

Overrides:

getYAxis in class PGSCanvas

getMinimumSize

public Dimension getMinimumSize()

rotate

public void rotate()

setLineType

public void setLineType(int nt)

Notifying

public void Notifying(NotifyMsg msg,
                      Object o,
                      Vector path)

Description copied from interface: Dependent

This method will be called when an even occured. Currently SMarker and Axis use this method of notification. There's no generic class for implemention the notification-list yet.

Specified by:

Notifying in interface Dependent

Overrides:

Notifying in class PGSCanvas

o - Object that sent the notification. The actual content is implementation-dependent.

path - This parameter is null for non-cascaded notify - in that case further calls to NotifyAll are not allowed. Otherwise it contains a Vector with all objects notified so far during cascaded notify. To aviod cyclic notifications every instance must either reject cascaded notifications (i.e. no calls to NotifyAll at all) or check for occurence of itself in the chain before calling NotifyAll. The only valid recursive calls in Notifying are NotifyAll(path) and NotifyAll(..,path), because only these two pass the "path" parameter to avoid cyclic loops.

paintPoGraSS

public void paintPoGraSS(PoGraSS g)

Description copied from class: PGSCanvas

abstract paint class to be implemented by any descendants.

Overrides:

paintPoGraSS in class PGSCanvas

mouseClicked

public void mouseClicked(MouseEvent ev)

Specified by:

mouseClicked in interface MouseListener

Specified by:

mouseReleased in interface MouseListener

mouseEntered

public void mouseEntered(MouseEvent e)

Specified by:

mouseEntered in interface MouseListener

mouseExited

public void mouseExited(MouseEvent e)

Specified by:

mouseExited in interface MouseListener

mouseDragged

public void mouseDragged(MouseEvent e)

Specified by:

mouseDragged in interface MouseMotionListener

mouseMoved

public void mouseMoved(MouseEvent ev)

Specified by:

mouseMoved in interface MouseMotionListener

keyTyped

public void keyTyped(KeyEvent e)

Specified by:

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 PGSCanvas

Parameters:

o - origin of the command

cmd - command string

Returns:

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

actionPerformed

public void actionPerformed(ActionEvent e)

Specified by:

actionPerformed in interface ActionListener
