How to refresh annotation after each frame?

I am trying to insert an output in an annotation outside of my plot. The value just keeps stacking on top of each other until it is unreadable. When I use the delete(findall(gcf,'Tag','stream') function it will delete the annotation and not refresh it like I am trying to do. Any suggestions?

annotation('textbox', [0 .6 .1 .2],'String','500 MHz Max Gain Slope (dB):','EdgeColor','none');
annotation('textbox', [0 .55 .1 .2],'String',Delta_band,'EdgeColor','none','Tag','stream')
delete(findall(gcf,'Tag','stream'));

After you're done with each frame, call

drawnow;

to force immediate refresh/repainting of the screen.

Thank you for a quick response! So do I even use the delete function with this? When I put drawnow; under my annotations I still end up with a movie that has the data stacked on top of each other.

I was able to put the delete function before the annotations and then use the drawnow; function after the annotations and it worked perfectly! Thank you again for the help!!!

for ind = 1:a

   delete(findall(gcf,'Tag','stream'));

   annotation('textbox', [0 .6 .1 .2],'String','500 MHz Max Gain Slope (dB):','EdgeColor','none');

   annotation('textbox', [0 .55 .1 .2],'String',Delta_band,'EdgeColor','none','Tag','stream')

   drawnow;

end
