See histfit

Ah, so...indeed that is pdf only...try something like--

y = evrnd(0,3,100,1);                   % some dummy data
[n,e]=histcounts(y);                    % counts with "best-guess" number bins
xhist=diff(e)/2+e(1:end-1);             % the resulting bin midpoints
[c,x]=ecdf(y);                          % empirical cdf points values vs position
hAx=plotyy(xhist,n,x,c*100,@bar,@plot)  % put above on one plot
ylabel(hAx(1),'PDF Hist')               % prettify up some...
ylabel(hAx(2),'CDF Plot')
