Let a(j) be the number of vehicles arriving between hour j-1 and hour j (j=1,...,24). So a is a row vector with 24 element.

Then do the following:

b(1)=0;

b(2:25)=cumsum(a(1:24));

b=b/b(25);

r=rand(1,10000);

random=interp1(b,linspace(0,24,25),r);

"random" gives you 10000 arrival times which lie between 0 and 24. If random(i) lies between integers j-1 and j (1<=j<=24)) means that the car arrives between hour j-1 and hour j.

But the number of EVs between hour j-1 and j (thus a(j)) is the y-value of your graphics from above, isn't it ?

Best wishes
