So lets say that I have an array of GPAs and Student IDs.
Info = [52211 3.55; 52922 1.79; 51939 3.33; 12140 0.81]
How can I plot the GPAs based on the their rank? So the GPA 3.55 is #1, 3.33 is #2, 1.79 is #3, and 0.81 is #4.

What kind of plot do you want? Scatter, line, bar, pie? Do you just want to have them against their rank? Labeled by their SID?

Scatter and just against their rank. The SID is essentially irrelevant.

Infos = sortrows(Info,2);
Infos = flip(Infos,1);
Infos(:,3) = [1:size(Infos,1)]';
scatter(Infos(:,3),Infos(:,2));
