keyControlPlugin

A figure plugin class usable as keyPress callback Function.

Description

A simple key-control plugin for plot figures

KEYCONTROLPLUGIN is a simple class whose 'KEYPRESSFUNCTION' method can be used as a KeyPressCallback function for plot figures in order to add basic key-enabled scrolling and zooming functionality.
 
    Usage example:
      t = 0:0.01:100 ;
      y = sin(t) ;
      c = keyControlPlugin('scrollFactor',0.25) ;
      plot(t,y) ;
  set(gcf,'KeyPressFcn',@c.keyPressFunction)
 
For more examples see the attached TESTPLOTCONTROL script.
 
Use this plugin in combination with LINKAXES in order to control
multiple plot figures, see examples
 
Options: (key-value style)
  ydisabled: [ false | true ], default: false
  zoomFactor: [ 0.1 ... 0.9 ], default: 0.5
  scrollFactor: [ 0 ... 1 ], default: 0.5
 
These keys are available in the current version:
  h ... list of available commands
  n ... next slice (jump by scrollFactor)
  b ... backwards (jump by scrollFactor)
  i ... zoom in (visiblerange = visiblerange*zoomFactor)
  o ... zoom out (visiblerange = visiblerange*(1+zoomFactor))
 
These modifiers are available
  Shift n ... jump to the beginning
  Shift b ... jump to the end
  Shift i ... zoom in (fast mode)
  Shift o ... show entire axis range
  Alt <COMMAND> ... apply any command to the y-axis
  AltShift <COMMAND> ... apply shift command to y-axis
 
Known issues:
  - In case the figure is not in default mode, the plugin may fail; it may even fail to be initialized. You will either notice no change or see a warning message. Use figure(...,'ToolBar','none')
in case you won't use the mouse anyway.
