Hi All,
I would like to know if there is a way to have the bin sizes change by
integer values. For example the bin size would be
10-20
20-30
not
10.3-20.5
20.3-30.5
and have it adjust as the number of bins changes.
Thanks

Wouldn't
X= np.ones((1, 45))
Y= np.zeros((32, 1))
change the existing values of the elements to ones and zeros?

I tested it out and it does change all the values to ones and zeros. Is there
a way to broadcast and keep the original values that were in the arrays?
Thanks for the help

Hi David,
I tried your fix

You should not change bins there, as you are evaluating the gaussian
function at different values.
Also, sigma is a vector, but it should be an scalar:
sigma
to make both
areas fit:
plt.plot(bins, N* N*(bins[1]-bins[0])**y, 'r--', linewidth=1)
And you will get a nice gaussian fitting your data.

Che,
You are correct on what I have to do. The problem is that I have a data
set
with ~1250 so I cant' do the sorting or finding the mean by hand
what you want to do? So you now want a histogram?

Hi Martin,
Thank for the relpy. What I have is a script that reads the data from
a large file then prints out the values listed in a particular column. What
I now need to do is have the information in that column plotted as the
number of rows vs. the mean value of all of the rows. What I
Hi,
I apologize if my explanation was less than clear. What I have is data in
a column that runs from row 1 to row 1268. In each each row there is a
number. For example
1
3
5
6
7
8
9
so I want the y axis to run from 1 to 7 ( the number of rows) and the x
axis to be the average of the

to programming, you may struggle, so I'd
suggest reading first going to scipy.org and reading up on numpy. When
you understand the basics of numpy, matplotlib's documentation should
make a lot more sense.
