Hi,
I have plotted my data but I need to add an equation in a textbox near to the lines in my plot. The textbox in the Insert seems to be not suitable as I need to use some symbols like gamma, tetha, alfa etc in the equation and these symbols are not available there. Or maybe I am wrong.
Any advice is appreciated much.

you can use the annotation command. e.g.
annotation('textbox',[0.1 0.1 0.1 0.1],'String','hello $\frac{2}{4} \alpha$ ','FitBoxToText','on','Interpreter','latex');
there you have any latex command available if you wish. or you use tex as interpreter

You can text() a label into position, and you can set the Interpreter property of the text() object to 'latex'
