function vis_PlaneAxisProperties(ax,lattice,msize,pos)

% VIS_PLANEAXISPROPERTIES Set axis properties for SOM_CPLANE, 
%                         SOM_PIEPLANE, SOM_BARPLANE and SOM_PLOTPLANE.
%
% vis_PlaneAxisProperties(ax,lattice,msize,pos)
%
%  Input arguments: 
%   ax        (scalar) axis handle     
%   lattice   (string) 'hexa', 'rect', 'hexaU' or 'rectU'
%             (matrix) defines the patch, see e.g. help vis_patch
%   msize     (vector) a 1x2 vector defining the grid size
%   pos       (vector) a 1x2 vector that determines position of
%                      origin or NaN which means default operation: 
%                      origin to [1 1] and tighten axis limits 
%                      according to the grid size.
% 
% This is a subfunction for SOM_CPLANE, SOM_PIEPLANE, SOM_BARPLANE and
% SOM_PLOTPLANE. This subfunction sets the proper values for axis.
