Hi, one way is to return output arguments and plot it yourself:

g = tf([1 0.1 7.5],[1 0.12 9 0 0]);
[magout,phase,w] = bode(g);
subplot(211);
semilogx(w,20*log10(squeeze(magout)));
grid on;
subplot(212)
semilogx(w,squeeze(phase));
grid on;


Compare to 1st help example in
>>doc bode

Hope that helps,
Wayne
