Putting Annotation on Plot Area

I have a plot of variables and a variable called 'name' which contains a string. I want to have a text box display the string contained in the variable named. I have the following code:

    figure
plot(SR,Pcr)
title('Critical Buckling Load vs Slenderness Ratio')
xlabel('Slenderness Ratio')
ylabel('Critical Buckling Load')
annotation('textbox',sprintf(name),'FitBoxToText','on');
  end
