import time varient data

I am trying to plot pressure change measured by a gauge, so just at one point, as time goes on. I have the data in excel saved as CSV, one column for time, and the other for pressure. Can I import the time data column or does PV use its own timesteps? Right now the only think happening is when I upload my data I use table to points and import the time and pressure values and I get basically a 2D graph of the data. What I want is to only see one pressure value magnitude at a time, so it would be an animation.
