LMP7721 Tina TI Noise Simulation

Hello,

  I'm simulating a simple transimpedance circuit with the LMP7721. The simulation runs fine and graphs the data appropriately.

My question lies in the data generated, when I export the graphical data as a txt file, the data is expressed in 3 columns:

Frequency | VM2-abs | VM2-phase

I would simply like to graph it like TINA-TI's graph is output, however I'm unsure what "abs" stands for and how to relate it to  V/HZ^2 the units displayed on the chart. 

Thank You.
