Hello there.

I'm using Live Script, and when I'm running my code:

W1 = tf(2, [0.001 0.111 1.11 1]);
bode1 = linearSystemAnalyzer('bode', W1)

I'm getting Linear System Analyzer window and a "screenshot" of it in my Live Script:

I want some additional information to be shown there, i.e. "Minimum Stability Margins". A pop-up window with a "Closed loop stable?" status would also be a good addition.

I know that I can set these things manually with a mouse, but the figure in my Live Script wouldn't be affected by these changes.

So I would like to know whether there are any fields in the linearSystemAnalyzer handler that can be set to show the necessary information (because I have not succeeded in finding them on my own).
