How to overlay my data point plot on Bode plot?

I did a hand-drawn approximation of the bode plot of a transfer function. Now, I am using MATLAB to plot the bode plot for me and then overlay my hand drawn plot on top of it. Is there a way to do that?

Z=[-10];
P=[-1,-100];
K=1000
G=zpk(Z,P,K);

x=[0.1, 1, 10, 100, 1000];
y=[0, -45, -45, -45, -90];
h=plot(x,y);
bode(G,h)

The code is giving me an error:

Probably the easiest way is to have bode return the data it calculates as outputs using the techniques in Obtain Magnitude and Phase Data and then create your own subplot figure for magnitude and phase to plot your data and the bode data.
