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')
title('PDF and CDF for Sampled Exponential')
Above results in

for a particular set of random values; your results will vary but be similar.

Assuming you can create the plots you need already..
I suggest you take a look at this: https://www.mathworks.com/help/matlab/creating_plots/plotting-with-two-y-axes.html
