2.2.2.2. How do I change the line style order on printouts?

The following is an M-file that allows you to cycle through the line styles in the order you want when you print:



function prtlines(a1,a2,a3,a4,a5)



% PRTLINES is a front-end to PRINT which converts



% solid lines to various line styles for graphical



% output.  The change is transparent to the user.



% Non-solid lines are not affected.



%



% PRTLINES is used in the same manner as PRINT.



%



% The default line styles are:



%



%   '. '



%   'o '



%   'x '



%   '+ '



%   '- '



%   '* '



%   ': '



%   '-.'



%   '--'



%



% The line style can be changed by editing the file



% and changing the 'styles' array.

styles = [

];



% Get the Children of the Figure.



a = get(gcf,'children');



% Check the Children of 'a'.  If they are



% solid lines, then change their LineStyle



% property.



for j = 1:length(a)



l = sort(get(a(j),'children'));



X = 0;



Add = 0;



for i = 1:length(l)



if strcmp( 'line', get(l(i), 'type' ))



if strcmp(get(l(i),'linestyle'),'-')



X = X + 1;



LINE = [LINE;l(i)];



SI =  rem(X,length(styles));



if SI == 0



Add = 1;



end



set(l(i),'linestyle', styles(SI+Add,:));



end



end



end



end



% Construct the PRTCMD.



PRTCMD = 'print';



for x = 1:nargin



PRTCMD = [PRTCMD,' ',eval(['a',int2str(x)])];



end
