I want to know how I can use another color than red on the bar in my WAITBAR figure.
h=waitbar(0, 'Please wait...')
for i=1:1000
     waitbar(i/1000)
end
close(h)

The “bar” in the WAITBAR figure is a patch object. Use the FINDOBJ function to find the patch handle. For more information about FINDOBJ, see the documentation:
 doc findobj
 or
 web([docroot '/techdoc/ref/findobj.html'])

To change the color of the patch you need to change its properties ‘EdgeColor’ and ‘FaceColor’. The example below describes how to do that:
h=waitbar(0, 'Please wait...');
hw=findobj(h,'Type','Patch');
set(hw,'EdgeColor',[0 1 0],'FaceColor',[0 1 0]) % changes the color to green
for i=1:1000
    waitbar(i/1000)
end
close(h)
For more information about PATCH properties see the documentation:
