Please Help.. How can I display a certain value in my plot?

Hello, I have a problem with my code.

My code gets some inputs then calculate the fuzzy membership function and gives the membership function graph. In the graph, I have a red cut-lined (--) plot which gives the calculated K parameter. But also I want to display the value of this in the graph. How can I do that with code?

A simple way would be to use the legend itself, something like this:

x=linspace(0,2*pi,100);
y=sin(x);
xmark=pi/4;

clf
plot(x,y); hold on; grid on
h=plot([1 1]*xmark,[-1 1],'--k');
legend(h,sprintf('X = %f',xmark))
