How do you turn off a polar grid while retaining a title?

Here is a slice of my longer code:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

theta = pi/2 : 2*pi/3 : 2*pi + pi/2;

r = ones(1,length(theta));

myline = polar(theta, r); title('Triangle')

%%

set(gcf,'Color','w');

set(0,'Showhiddenhandles','on')

extrastuff = setdiff(get(gca,'children'),myline);

delete(extrastuff)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

I grabbed the second portion of code online to get rid of the polar axis, but it destroyed my title as well. Please help, thanks. :)

If all you want is the triangle and the title, then this will work:

theta = pi/2 : 2*pi/3 : 2*pi + pi/2;

r = ones(1,length(theta));

myline = polar(theta, r); ht = title('Triangle');

set(gcf,'Color','w');

set(0,'Showhiddenhandles','on')

extrastuff = setdiff(get(gca,'children'),[myline ht]);

delete(extrastuff)

Notice that what I did was to get the handle of the title, and add that handle to the list of ones not to delete (in the second argument of your setdiff command).

Thank you so much! :)
