My work is based on real time data acquisition and I am plotting the data in real time. My program currently reads 200 sets of data per second. I have used
drawnow limitrate
to speed up the process. But is there any way to reduce the frame update to 10 per second?
I also have annotation that specify values of peaks which will be also be updated with all 200 sets of data. Does drawnow work on annotaion as well or will it just work on plot?
Thank you for any help.

figure;
axes('NextPlot', 'add');
tic;
while 1
plot(rand, rand)
if toc > 0.1
drawnow;
tic;
end
end
drawnow triggers the update of the contents of the figure. This concerns annotations also.
