remove annotations from diskmarginplot

Hey guys! I want to show a system's stability by giving the system's diskmargin by some skew variations. To give a smooth shape of the stable area of the system in complex plane, i stacked all the diskmargin variation by using this script:
% Plant Model
f = pos_motor;
% Plant Diskmargin
s_DOL = -100:1:100;
figure(1)
hold on
for i = 1:numel(s_DOL)
DOL = diskmargin(f,s_DOL(i));
diskmarginplot(DOL.GainMargin,'disk')
end
hold off
And this results in a figure:
The description for each diskmargin on the figure is quite a bother. I searched for the solution in function diskmarginoptions but with no success.
Hope anyone can help! Thanks

Hi Muhammad,
Something like this might work, either inside or after the loop. Some experimentation may be needed.
Disk margin plot with annotations.
L = tf(25,[1 10 10 10]);
DM = diskmargin(L);
DGM = DM.GainMargin;
DPM = DM.PhaseMargin;
diskmarginplot(DGM)
Copy the plot to see how it changes
copyobj(gca,figure);
Find the text objects
h = findobj(get(gca,'Children'),'Type','Text')
Delete them
delete(h)
