MATLAB: Histogram to a CDF/PDF

Question

Hello, This is a screenshot of a table I have constructed for work.

Just to play it safe, I blacked out the column names, though it would be hard to assume anything with just 7 rows of the table to go off of. We will call the 5 fields "column1, column2, etc."

So I am able to create the hisogram of any of the columns, besides 3, but that isn't needed because it is all '94'.

I do:

histogram([a(1:135756).column1])

and the histogram works perfectly.

How would I do a CDF or PDF of this data?

I have tried:

histogram([a(1:135756).column1],'Normalization',pdf)

or

histogram([a(1:135756).column1],'Normalization',cdf)

but nothing changes from the original histogram.

Thank you!

Answer 1

A=[a(1:135756).column1];
figure
subplot(2,1,1);
histogram(A,'Normalization','pdf');
ylabel('pdf');
subplot(2,1,2);
histogram(A,'Normalization','cdf');
ylabel('cdf');
