Converting a weibull figure to a histogram

I created a weibull distribution based on hours of the day. I would like to have a histogram to further show these results. How can I obtain the histogram?

The code for the weibull distribution is:

x=0:1:23;

y=wblpdf(x,3,2);

y_new=round(4000*y);

y_new=circshift(y_new,16);

figure(1)

plot(x,y_new)

I tried using histogram(y_new) and histfit(y_new), even adjusting number of bins, but the figures I got were very different

Any tips please?

histogram takes a list of data values (your x's) and tabulates how often each occurs. if you don't already have data values, you might generate some randomly, e.g.

sample_data = wblrnd(3,2,10000,1);
histogram(sample_data); % 'normalization','pdf');

The extra (now commented) parameters on the histogram command will put the histogram heights on the same scale as the pdf values from wblpdf.
