Using a thermocouple, how do I get measurements with reference to time?

[fobbernob]

I have a thermocouple wired to an XY graph but when I run the application the Y-axis takes the data but does not move along the X-axis, with reference to time, while plotting each new data point. This is to say that I have a completely vertical plot of points for different temperatures a time=0 or x=0.

It sounds like you're not correctly updating the array of x values that contain the time. Unless your acquisition time is not constant, then it's usually easier to use a graph or chart for plotting something versus time. It's pretty automatic then instead of having to do some coding. Could you explain in more detail how you're creating the x axis values or maybe attach the program.
