How to write variables values on a figure?

Hi, in my script i would like to write some variables values on a figure that i call it from a pushbutton Gui oriented. How can i call the figure in the right way and writting on it in a specific position of my picture.

PS: Notice i won't have axis to be oriented, but i don't know if this will be a problem or not.

Thanks in advance!

This is an example

t=1:.01:10;
d=1; % here d is variable
dim=[0.5, 0.2, 0.1, 0.1]; %From here you can location the position of text
plot(sin(t));
str=sprintf('%.2f',d); %if No floting varibale number, use %d
annotation('textbox',dim,'String',str,'FitBoxToText','on');

Hi Kalyan, thank you for you answer!

The figure i want to show is a .jpg file and i want to write on it, it's not a plot, i've tried to do it in the way you said but didn't worked for me.

d=1;
im=imread('test.jpg');
position=[1 50];
box_color ={'red'};
text_str=sprintf('%.2f',d);
RGB=insertText(im,position,text_str,'FontSize',18,'BoxColor',box_color,'BoxOpacity',0.4,'TextColor','white');
figure
imshow(RGB)
