function chart( fontname )
% CHART Show ANSI-chart like display of characters MATLAB can produce.
%       CHART( 'fontname' ) will through up a figure window with all
%       255
%       characters of the named font in a 16x16 grid.
%       Close figure when done, it creates 256 text objects. You may
%       want
%       that memory back!

% TO USE THIS CHART:  USE SETSTR( VALUE), WHERE VALUE=( (16*XCOORD) +
% YCOORD )

%make a new figure  and axis
%( I'm assuming you want to keep the current graph in the gcf. )

%set font to be used

set(ax, 'DefaultTextFontName', fontname )
