MATLAB: Plotting certain columns from a .dat file

.dat file

Greetings all,
It's been quite some time since I've used MATLAB, and embarrasingly I've been struggling with this all day. Needless to say I am a bit rusty! I have a data file that has 8 columns of data (and has headers at the top). Right now I'm trying to just plot column 2 of the data on the x-axis and plot the 4th and 8th columns as two line plots along the y-axis.
   I imagine you use fopen and textscan, but there's so many to choose from. Maybe importdata?
    Any help would be appreciated. Thanks!

If your data file format is consistent, try
data=importdata('MyFile.data');
For plotting, if you have a matrix A, A(:,2) is all the data in the second column so you can do:
plot(A(:,2),A(:,4),'r',A(:,2),A(:,8),'b');
