I want to display a value on the plot...my code is as follows..

plot(a,b);
hold on
plot(a,c);
axis([400 850 0 1]);
legend('first','second');
text(465,0.9,'Value=N(i)');

I want to display the value stored in N(i) on the plot.When i used this code it displaying just that string. Instead i want to display the value stored.Thanks in advance!

When specify N(i) in a string, it doesn't know that you're actually
trying to access a variable. Try something like:

text(465, 0.9, sprintf('Value=%d', N(i)))

text(465,0.9,sprintf('Value=%f',N(i)));

.... or, if you'd like to do it the Matlab way:

text(465,0.9,['Value=' num2str(N(i)) ]);
