How to determine unretained compound from chromatogram

From reading my text and the web I'm not 100% clear on how to see what compound is unretained from looking at a chromatogram. Is it always the peak with the smallest retention time?
I'll see images like the one below and that's what I'm led to believe...

Not necessarily. But this is a good picture that you've found. Have you learned anything else from it? What do V

and T

stand for? And more important than the name, what do they mean?

Hey, I'm not judging. I just like to shoot straight. I'm a man of science.
