What doesn't it work? Are you getting an error message? If yes, please copy and paste it here; if no, please specify what's wrong.
I'm assuming the variable you're trying to plot is named 'a'.
Lastly, if you're using a more recent version of matlab, use histrogram() instead of hist().

First read about the output to the load() funciton:
The output is a structure containing fields for each variable in the file.
Suppose the variable you're trying to plot is named 'data'
a = load('partOneData.mat'); %'a' is a structure
figure
histogram(a.data) % 'data' is the name of the variable you're plotting
