Thread Subject: How to zoom in the graph?

Hye everyone...

I want to ask...how to enlarge/zoom in the magnitude and phase graph
that is obtain from fft process?
Here is the codes:

%FFT computation
xx = image1; % Signal
yy = fft(xx); % Compute DFT of x
mm = abs(yy); p = unwrap(angle(yy)); % Magnitude and phase
ff = (0:length(yy)-1)*99/length(yy);% Frequency vector
axes(handles.axes7);
plot(ff,mm); title('Magnitude');
set(gca,'XTick',[20 40 60 80]);
axes(handles.axes8);
plot(ff,p*180/pi); title('Phase');
set(gca,'XTick',[20 40 60 80]);

Look forward for the solution...Thanks....

In the figure window, click on the zoom bottom. it is at the top panel above
your figure, right there, keep looking and you should see it if all is
normal. Use the mouse to zoom in/out.

good luck
