You can use the Scan From String to get a timestamp (%<%H:%M:%S>T) or relative time (%<%H:%M:%S>t) but since you have repeated times, your graph is going to show different y values for the same x.

Take a closer look at the format string you are using versus the one in the Snippet.

Then go to Graph Properties -> Display Format and set the X-Axis format to Relative Time.

Why did you use "f" in your format string and not "t" or "T"? That is what Darin is talking about.
