Adjust signal to plot

Hi!

I'm making a GUI with some axes and I want to adjust the signal to the full space of the axes. Here's an example:

As you can see, in the first Axe the signal is shown in just half of the space I created, and I want both, the signal plot and the pitch (Axes 2) adjusted to the full space.

this is my code:

   [sample,fs]=wavread(name);
    axes(handles.axes1);
    dt = 1/fs;
    time = 0:dt:(length(sample)*dt)-dt;
    plot(time,sample);
    axes(handles.axes2);
    [F0, T, C] = spPitchTrackCepstrum(sample, fs, 30, 20, 'hamming');
    plot(T,F0);
    axes(handles.axes3);
    specgram(sample, 1024, fs);colormap(jet);colorbar;xlabel(''); ylabel('');

Thanks!

Figure out where the last element is and use xlim. Let's say the last element is length(sample). Then do

xlim([1, length(sample)]);

Do that after each call to plot().
