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().
Thank you for your reponse this is the error
Error using histogram
Expected input number 1, x, to be one of these types:
double, single, uint8, uint16, uint32, uint64, int8, int16, int32, int64, logical, datetime, duration
Instead its type was struct.
Error in histogram>parseinput (line 250)
validateattributes(x,{'numeric','logical','datetime','duration'},...
Error in histogram (line 145)
[opts,passthrough,dispatch] = parseinput(args,firstaxesinput);

histogram(a)

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
Also see this example:
