I am unable to find an effecive method to bin the following data.
11.8652 3.5891
12.5513 6.6741
11.8652 3.5891
8.8125 1.1711
8.8125 2.3422
8.8125 1.1711
5.7598 0.3324
5.0737 0.9444
5.7598 0.3324
12.5513 6.6741
14.1000 19.0596
12.5513 6.6741
8.8125 2.3422
0.0000 0.0000
8.8125 2.3422
5.0737 0.9444
3.5250 7.2712
5.0737 0.9444
11.8652 3.5891
12.5513 6.6741
11.8652 3.5891
8.8125 1.1711
8.8125 2.3422
8.8125 1.1711
5.7598 0.3324
5.0737 0.9444
5.7598 0.3324
For example I am trying to
Energy = Sum
14.1000 = 19.0596
12.5513 = 6.6741 + 6.6741 + 6.6741 + 6.6741
11.8652 = 3.5891 + 3.5891 + 3.5891 + 3.5891
8.8125 = 1.1711 + 1.1711 + 1.1711 + 1.1711 + 2.3422 + 2.3422 + 2.3422 + 2.3422
so on and so forth
I would like to then plot(Energy,Sum) while not repeating the Energy. I cannot find away to do this. I appreciate the help.

[uvals, a, uidx] = unique(YourData(:,1));
Sum = accumarray(uidx, YourData(:,2));
plot(uvals, Sum)

Make an array with A=[energy sum] Then use:
A=sortrows(A);
hist(A(:,2),A(:,1))
