Use annotation function changing the string dinamycally
显示 更早的评论
Hi,
I want to create a text in a figure but outside the axis, but it has to change with the time according to some pressure sensors. I am using "annotation" function:
loop:
steps=steps+1;
txt = ['Steps number: ' num2str(step_number) ' units'];
annotation('textbox',[.9 .5 .1 .2],'String',txt,'EdgeColor','none');
The issue is that the value it's being overlapped each iteration. Could someone help please? Thanks

Create the annotation once, and then only change the string property inside the loop.
figure(1)
txt='';
h_annot=annotation('textbox',[.9 .5 .1 .2],'String',txt,'EdgeColor','none');
for steps=1:5
step_number=steps;
txt = sprintf('Steps number: %d units',step_number);
set(h_annot,'String',txt)
drawnow%force graphics update, pause(0.001) will work as well
for k=1:1e6
1+1;%have some calculation to simulate your actual processing time
end
end
