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
8
5
1
3
2
1

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');

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?
