Use xticks from file

Hi Guys

Is there an eays way to plot a number vs a label from a file?

Here is an example
I have a datafile like this:
#Aa Bb nA nB Surf Bulk segEnergy
Fe Cr 19 1 -909.065612 -909.060586 -0.100520
Fe Ni 19 1 -855.708731 -855.700865 -0.157320
Fe Mo 19 1 -810.257339 -810.252167 -0.103440

I want to plot the last row vs the second row.

Now i have to do:
y,dummy = load(‘data.dat’,usecols=(6,6),unpack=True)

Is there an easy way to do this?

And why does usecols=(6) not work?
