Daniel@0: %  Input arguments: 
Daniel@0: %   ax        (scalar) axis handle     
Daniel@0: %   lattice   (string) 'hexa', 'rect', 'hexaU' or 'rectU'
Daniel@0: %             (matrix) defines the patch, see e.g. help vis_patch
Daniel@0: %   msize     (vector) a 1x2 vector defining the grid size
Daniel@0: %   pos       (vector) a 1x2 vector that determines position of
Daniel@0: %                      origin or NaN which means default operation: 
Daniel@0: %                      origin to [1 1] and tighten axis limits 
Daniel@0: %                      according to the grid size.

Daniel@0: % This is a subfunction for SOM_CPLANE, SOM_PIEPLANE, SOM_BARPLANE and
Daniel@0: % SOM_PLOTPLANE. This subfunction sets the proper values for axis.
