Function Synopsis

tightmap(style)

Help text

TIGHTMAP removes whitespace around a map
 
   TIGHTMAP sets the MATLAB axis limits to be tight around the map in the 
   current axes.  This eliminates or reduces the white border between the 
   map frame and the axes box.  Use AXIS AUTO to undo TIGHTMAP.
