plot probability density function

Hi all, I've tried to plot probability density for a give diagram but I could not reach the same figure as in the book.

I attached a picture for the question.

Here is the data on X-axis

0-5000

5000-10000

10000-15000

15000-20000

20000-25000

25000-30000

30000-35000

35000-40000

40000-45000

45000-50000

50000-55000

55000-60000

The corresponding data on Y-axis:

8

9

8

13

5

1

Please show the code that you have tried.

Hi...

 This code surely will help you.

 a=5000:5000:60000;
 b=[8 9 8 13 8 5 1 3 2 1 1 1]
 bar(a,b);
or
stem(a,b);

That is good for the left part of the attached picture (histogram).

But How about the probability density function (on the right part of the picture?

waiting for your helps :)

Thanks!

Hi... check this for second plot

a=5000:5000:60000;
b=[8 9 8 13 8 5 1 3 2 1 1 1]
scatter(a,b); hold on
plot(a,b,'m');

[Hisham]

Actually is not similar to the curve as in the attached picture. I think the curve is plotted by using the probability density function, but I don't know how can I use it?

How can calculate propability density function of image without using imhist command or own code
