Method Detail


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.

updateObjects in class BaseCanvas


public java.lang.String queryObject(int i)
queryObject in class BaseCanvas


public void keyTyped(java.awt.event.KeyEvent e)
Specified by:
keyTyped in interface java.awt.event.KeyListener
keyTyped in class BaseCanvas


public java.lang.Object run(java.lang.Object o,
                            java.lang.String cmd)
Description copied from class: PGSCanvas
default handing of commands "exportPGS" and "exportPS". Any descendant should call,cmd) to retain this functionality

Specified by:
run in interface Commander
run in class BaseCanvas
o - origin of the command
cmd - command string
any object, the actual interpretation is up to the calling object


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.
