Add text description to point of a selected subplot

Hi

I plot bode diagram of a transfer function in matlab by bode(F) function in matlab livescript. As it is known this plot consist of two subplot: upper is amplitude and lower plot is phase. I am trying to add a text description to a point in upper plot but when I use the text command it draws in the lower phase plot. Can you guide me how to add text to upper plot?

Just point to the first subplot using simply:

subplot(2,1,1);
text(x,y,'my text here') % EDIT: This method does not work, see below 

EDIT: plot manually the bode, as described below!

bode(Ia_ph_A_2);

subplot(2,1,1);

Point_1 = ['\leftarrow ' 'Freq= ' num2str((w1 + w))];

text((w1 + w),mag2db(alpha_A_1),Point_1)

it is not working. I have almost tried it... It just add a new empty plot at the end

You are reason...

The only suggestion that I can give you is to plot the bode "manually".

[mag,phase,w]=bode(MyModel);   % Extract magnitude, phase and pulsation

figure('name','MyFig');        % Then plot the arrays
subplot(2,1,1)
loglog(w/(2*pi),squeeze(mag));
Point_1 = ['\leftarrow ' 'Freq= ' num2str((w1 + w))];
text((w1 + w),mag2db(alpha_A_1),Point_1)
subplot(2,1,2)
semilogx(w/(2*pi),squeeze(phase));

Hope that can help you. Maybe other users can help you more efficently.
