Adding annotations to Bode plots.

Hello I would like to add annotations to my bode plot exactly like

Here is my code to the systems

TF1=tf(1,[1 1]);
TF2=tf(16,[1 4 16])
bode(TF2,'b--',TF1*TF2,'g')
grid on
legend('w/o actuator','w/ actuator')

it is easy to add line and text in plots directly from figure. Go to insert tab in menubar of figure and select whatever you want to draw on figure

if you want to do it by coding, see here

[Mirlan Karimov]

textbox1 = uicontrol('Position',[0 0 0 0],'Style', 'text','Units','norm','fontweight','bold','fontsize',14);

set(textbox1, 'String', 'Your Text Goes Here');

By the vector shown in bold, you can play around with the position of the textboxs

The line would have to be -20dB. How would I do that?
