Multiple Bode plots on same graph, how to plot phase ?

Hello,
My question has already been posted, but I'm having some trouble...
I'm trying to plot 2 bode plots on the same figure. One of the plots has a transfer function, the other not. So I use this command:
semilogx(x,y), hold on
bode(sys, 'r')
On this way I get 2 curves on the amplitude-plot, to this point all right. I'm looking to also add a second curve on the phase-plot. I tried using subplot(2,1,2), but it doesn't work...
Does anyone can tell me how to add this second phase-cure?
Thanks, Ata

Could you post an example of what you'd like and what you actually get? It doesn't work is not a very helpful description. Have you tried

[mag_A phase_A] = bode(sys_A,W);
[mag_B phase_B] = bode(sys_B,W);
subplot(2,1,1)
semilogx(W,mag_A);hold on
semilogx(W,mag_B);hold off
subplot(2,1,2)
semilogx(W,phase_A);hold on
semilogx(W,phase_B);hold off
