I feel I see the light at the end of the tunnel. The npz file is even not necessary, I just need to pass the star id to a separate plotting process, to be compared to some stored previous value, in order to refresh the plot. I have to think about it for a couple of days… Thanks for the suggestion, Cheers, JB-- Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
[Matplotlib-users] import problem (matplotlib ? numpy ?) on Mac Intel, python 2.6
Dear matplotlib/numpy gurus,
This is my first attempt to use matplotlib & numpy, with the following small
piece of code:
#!/usr/bin/env jython jython because of the import of stilts from
starjava
# Fabrique les figures des champs du papier Catalogue
__author__="marquett"
__date__ ="$16 mai 2011 12:17:08$"
import sys
sys.path.append('/star/starjava/etc/ttools')
sys.path.append('/Library/Frameworks/Python.framework//Versions/2.6/lib/python2.6/site-packages')
import stilts
import glob
import matplotlib.pyplot as plt
I got the following trace:
Traceback (most recent call last):
File "/Users/marquett/Downloads/FigCat/src/figcat.py", line 14, in

line 5, in
import multiarray
ImportError: No module named multiarray
I use the latest 1.6.0 version of numpy and 1.0.0 one of matplotlib.
My so little experience tells me that this is a deep numpy issue rather than a
matplotlib one.
Any hint welcome, thanks.

Re: [Matplotlib-users] [AstroPy] import problem (matplotlib ? numpy ?) on Mac Intel, python 2.6
Hi Thomas,
AtPy looks great. My only concern with starjava was to use stilts
functionalities for managing ascii tables and coordinates transformations from
degrees to sexagesimal and reverse. But I guess that AtPy deals with headers
having a leading "#" and names of columns, like
# idra_min ra_max dec_min dec_max
and that pywcs can do transformations. So I can switch to pure python scripts.
Cheers,
JB
