How to plot amplitude against frequencey?

Subject: How to plot amplitude against frequencey?

I'm using LabView to get real-time signals from a spectrum analyzer as shown below.
http://i21.photobucket.com/albums/b272/yusof_hardy/signal.jpg.

The data is written to a file
http://www.autoplasm.com/09Oct24.fsp


The question is how do I plot the amplitude against frequency graph in Matlab just like the one done by LabView?



data = load('09Oct24.fsp');
amplitude = data(:,2);


Now how do I plot amplitude vs frequency graph with frequency axis ranging from 1.2000E+9 to 1.4000E+9 at a specific time?
