I am trying to use 'text' to write something in my plot
but after running nothing appears
Can any one knows what is the problem ?


text(1000,1000,'string') ....
or

text(5*pi/4,sin(5*pi/4),...
['sin(5*pi/4) = ',num2str(sin(5*pi/4))],...
'HorizontalAlignment','center',...
'BackgroundColor',[.7 .9 .7],...
'Margin',10);

try this
plot(0:pi/20:2*pi,sin(0:pi/20:2*pi))
text(pi,0,' \leftarrow sin(\pi)','FontSize',18)
