A simple key-control plugin for plot figures

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) ;

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.

System Requirements:

MATLAB 7.12 (2011a)
Program Release Status: New Release
Program Install Support: Install and Uninstall
