In R2024b how to read the Y tick labels of a bode plot

In matlab 2024b how do I read the Y tick labels of a bode plot? Here is an example script that works in R2022b

sys = rss(1);
figure;
bode(sys)
axis = gca;
points = get( axis , 'Ytick' );

Which gives the result

points =

-15   -10    -5     0

But in R2024b it gives the error Unrecognized property Ytick for class controllib.chart.BodePlot.

Any ideas how to do this in this version?

Here is the corrected code:

% TF of the given system:
sys = rss(1);
% BODE Plot:
H=bodeplot(sys); % Generate Bode plot and get handle

●

% Get MAG and PHASE axes handles:
AX = findall(gcf, 'Type', 'axes');
% Extract Y-tick LABELS:
MAG_yticks = yticks(AX(1)); % MAGNITUDE plot
MAG_yticklabels = yticklabels(AX(1));

PHASE_yticks = yticks(AX(2)); % PHASE plot
PHASE_yticklabels = yticklabels(AX(2));

% Display the RESULTS:
disp('MAG Y-tick Labels:');

MAG Y-tick Labels:

disp(MAG_yticklabels);

    {'-6'}
    {'-5'}
    {'-4'}
    {'-3'}

disp('PHASE Y-tick Labels:');

PHASE Y-tick Labels:

disp(PHASE_yticklabels);

    {'0'  }
    {'45' }
    {'90' }
    {'135'}
    {'180'}

Thank you, this is what I need. It also works with bodemag and bode.
