LEGEND  LEGEND Add Legent to Plot


Usage
 
 This command adds a legend to the current plot.  Currently, the
 following forms of the legend command are supported.  The
 first form creates a legend with the given labels for the data
 series:
 
   legend('label1','label2',...)
 
 where 'label1' is the text label associated with data plot 1
 and so on.  You can also use the legend command to control
 the appearance of the legend in the current plot.  To remove the
 legend from the current plot, use
 
   legend('off')
 
 To hide the legend for the current plot (but do not remove it)
 
   legend('hide')
 
 And to show the legend that has been hidden, use
 
   legend('show')
 
 You can also toggle the display of the box surrounding the legend.
 Use
 
   legend('boxoff')
 
 or 
 
   legend('boxon')
 
 to turn the legend box off or on, respectively.  To toggle the
 visible state of the current legend, use
 
   legend('toggle')
 
 Specifying no arguments at all (apart from an optional location 
 argument as specified below) results in the legend being rebuilt.
 This form is useful for picking up font changes or relocating the
 legend.
 
   legend
 
 By default, the legend command places the new legend in the 
 upper right corner of the current plot.  To change this behavior,
 use the 'location' specifier (must be the last two options to the command)
 
   legend(...,'location',option)
 
 where option takes on the following possible values
   -  north,N - top center of plot 
   -  south,S - bottom center of plot
   -  east,E - middle right of plot
   -  west,W - middle left of plot
   -  northeast,NE - top right of plot (default behavior)
   -  northwest,NW - top left of plot
   -  southeast,SE - bottom right of plot
   -  southwest,SW - bottom left of plot
 This implementation of legend is incomplete relative to the 
 MATLAB API.  The functionality will be improved in future versions
 of FreeMat.
