I'm looking for a command that will plot a phase Bode plot of a transfer function, but not a magnitude plot. I'm doing this to compare my own plot (from data instead of a transfer function) with a plot made from a TF.
I've already used
bodemag(tf)
to plot a magnitude-only Bode plot, but I can't find anything similar for phase. I've tried several variations of this command and looked around the bode() documentation but I can't find anything.
Does anyone know if there's a command, and if not how do I plot a phase-only plot so that it can be compared?

Reposting Tommy's comment here as its the solution for any future users:
h = bodeplot(tf);
setoptions(h,'MagVisible','off');
