instantaneous phase angle plots?

Hello, I'm struggling with this last part of an instantaneous phase angle plots.
I know how to get the phase angle
yh=hilbert(data);
amplitude=abs(yh);
phase=unwrap(angle(yh));
But I want to get the sawtooth plotting of phase angle(see link image for example).
I can't seem to figure out this last part. Any help? thank you.
extra question:
Also, why aren't the values of the phase angle normalized? that is, shouldn't they always go from pi to -pi? I have a noisy signal and the extrema of the phase angle plot range from 0.2 to 0.5
