AXIS  AXIS Setup Axis Behavior


Usage
 
 Control the axis behavior.  There are several versions of the
 axis command based on what you would like the axis command to
 do.  The first versions set scalings for the current plot.
 The general syntax for its use is
 
   axis([xmin xmax ymin ymax zmin zmax cmin cmax])
 
 which sets the limits in the X, Y, Z and color axes.  You can
 also set only the X, Y and Z axes:
 
   axis([xmin xmax ymin ymax zmin zmax])
 
 or only the X and Y axes:
 
   axis([xmin xmax ymin ymax])
 
 To retrieve the current axis limits, use the syntax
 
   x = axis
 
 where x is a 4-vector for 2D plots, and a 6-vector for
 3D plots.
 
 There are a number of axis options supported by FreeMat.
 The first version sets the axis limits to be automatically
 selected by FreeMat for each dimension.  This state is the
 default one for new axes created by FreeMat.
 
   axis auto
 
 The next option sets all of the axis limits to manual
 mode.  This state turns off automatic scaling of the axis
 based on the children of the current axis object.  
 
   axis manual
 
 The next option sets the axis limits to fit tightly around
 the data.
 
   axis tight
 
 The next option adjusts the axis limits and plotbox aspect
 ratio so that the axis fills the position rectangle.
 
   axis fill
 
 The next option puts the axis in matrix mode.  This mode
 is equivalent to the standard mode, but with the vertical
 axis reversed.  Thus, the origin of the coordinate system
 is at the top left corner of the plot.  This mode makes
 plots of matrix elements look normal (i.e., an identity
 matrix goes from upper left to lower right).
 
   axis ij
 
 The next option puts the axis in normal mode, with the origin
 at the lower left corner.
 
   axis xy
 
 The next option sets the axis parameters (specifically the
 data aspect ratio) so that equal ticks on each axis represent
 equal length.  In this mode, spheres look spherical insteal of
 ellipsoidal.
 
   axis equal
 
 The next option is the same as axis equal, but sets the
 plot box to fit tightly around the data (so no background shows
 through).  It is the best option to use when displaying images.
 
   axis image
 
 The next option makes the axis box square.
 
   axis square
 
 The next option restores many of the normal characteristics of
 the axis.  In particular, it undoes the effects of square
 image and equal modes.
 
   axis normal
 
 The next mode freezes axis properties so that 3D objects can
 be rotated properly.
 
   axis vis3d
 
 The next mode turns off all labels, tick marks and background.
 
   axis on
 
 The next mode turns on all labels, tick marks and background.
 
   axis off
 
 The next mode is similar to axis off, but also repacks the
 figure as tightly as possible.  The result is a plot box that
 takes up the entire outerposition vector.
 
   axis maximal
 
 The axis command can also be applied to a particular axis
 (as opposed to the current axis as returned by gca) handle
 
   axis(M,...)
