+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.
