How to label a graph in Matlab

Question

I have created a Matlab plot with two graphs within one figure. I have plotted the graphs in colour and set up a legend. But now, I want the graph to be understandable in black and white print as well. Therefore, I want to label the graphs directly. I have tried:

text(P_in,P_out,{'AM/AM'});

But this, clearly doesn't work. Here is the figure:

Answer 1

To place text in a graph, use

text(x, y, 'Example text')

where x, y are numbers between 0 and 1 specifying the text position within the current axes.

You can also use

gtext('Example text')

and select the text position with the mouse.
