It's the same syntax as an import statement such as the following:
import numpy as np, matplotlib as mpl

Hi Andre,
I figured it out. Need not reply of np.savetxt for storing array simply
f.wite() is doing fine.
while i < 999:
print i
fo.write('{0:f} {1:f} {2:f}\n'.format(pp_za[i], pv_za[i],t))
i = i + 1
Eager to know that single file thing though!

Hi Andre,

You should not need many data files to make an animation. If you write your
loops correctly, you can take a single data file with all the data. If y
Yup it's exactly what I want!
I want *many* data files,not one...to make an animation out of it. For a
data file t is constant.
the solution you have just mentioned i.e np.array([t,pp_za,pv_za]) is
giving the following error:
Traceback (most recent call last):

Hi Alan,
Sorry for the ambiguity I have created.
I have added the snippet of code just in the previous mail and also the
sample data in the text file. Have you had a look on them?
I am copy pasting it in this email:

Can you define what that means?
All files on a computer are data files in some sense.
They exist as text files or binary files. If they are text files then

Thank Andre for your prompt answer.
I'll figure out the plotting issue once the dat files are made. So it's the
primary concern.
For an example I am attaching a dat file herewith. The two columns here are
2 numpy arrays.I want to add a third column, to be precise, I want to print
a parameter value
Hi Sayan,
This question would be better suited to the matplotlib list.
Also, a more precise description of your existing data, and what you hope it
would look like would make it easier to help answer your question. Eg., from
your description, it is not clear if your existing data is in a table,
24 matches
