Change rlocus() axis units to Hz?

How can I change the plotted rlocus() real axis units to Hz, vs rad/s?
I tried Property Editor --> clicking on X axis --> More Properties --> Units --> Frequency field --> Hz, but didn't seem to change the plot.
I tested with a single pole at -10, plotting 1/(s+10), and the pole remained at -10 regardless of Hz or Rad/s setting.

sys = tf([2 5 1],[1 2 3]);
hrlp = rlocusplot(sys);
opts = getoptions(hrlp)
setoptions(hrlp, 'FreqUnits','Hz')
Second, it doesn’t display frequency values or units, although you can certainly set them. (The same options are available on other plot functions. For a full list of the available plot functions, see the setoptions documentation section p.)

Clarified code. No substantive changes.
