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

13

Please show the code that you have tried.

Hi...
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?
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');

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
