How to get text that is dynamic on a graph?

So I'd like to get a graph that changes as variables change. I have played with this test to try to get rotating text but for some reason, the graph does not open until after I pause or quite the while loop. Just curious if there is a better way to do what I'd like to do
axis([0 5 0 5]);
a =0;
while true
a =a +1
h=text(2.5,2.5,'Rotated text','rotation',a);
delete(h)
end

In general figures do not update while code is running. To force an update while code is running use drawnow
axis([0 5 0 5]);
a =0;
while true
a =a +1
h=text(2.5,2.5,'Rotated text','rotation',a);
drawnow();
delete(h)
end
