Hello,
I'm trying to plot some grid data using basemap and imshow however
haven't figured out how to specify the color for nan values.
For example, in my data, valid values range from 0.0-10.0. I've
assigned -9999.0 and 1e30 to the missing values and when I imshow
(setting vmin=0.0, vmax=10.0), the missing values show up in the
low and high end of the spectrum, respectively. Is there a way
to do this?
Thanks,
Gerald

Can anybody think of a good way to disable a widget (specifically
SpanSelector) during plot interaction from the toolbar? It seems
wrong when you are panning and the SpanSelector is triggering over and
over. Is there a trivial way to detect the state of the toolbar?
Thanks,
 Charlie

If I say:
my_array =3D -my_other_array
I get the correct result.
However, if I say:
my_array =3D +my_other_array
Weired things happen...
It worked fine using numarray-1.3.3...
Part of my code looks as follows:
...
#Input current as a function of the output current
ia=3D0
ib=3D-iA
ic=3D+iA
iip_cbb=3Dsqrt(2.0/3)*(ia+ib*exp(-2j*pi/3)+ic*exp(+2j*pi/3))
...
The error code I get is:
>>>
Traceback (most recent call last):
File "C:\My Documents\My PhD\Python\helle\helle.py",
line 229, in ?
iip_cbb=3Dsqrt(2.0/3)*(ia+ib*exp(-2j*pi/3)+ic*exp(+2j*pi/3))
TypeError: unsupported operand type(s) for *: 'dict'
and 'complex'
>>>
I then "debuged" the results:
>>> ia
0
>>> ib
array([ -2.30940108e+02, -2.30061311e+02,
-2.27431609e+02,

2.30061311e+02,

It looks fine.

Gives the same result...
Most of the garbage looks like matplotlib stuff...
I know the solution is to say:
...
ic=3DiA
...
without the "+", but this is a bug somewhere...
Kind regards,
Peter-Jan

OK,
matplotlib-0.85 gives the identical error.
Installing the newest SWIG was also a failure
for whatever reason.
It's a pitty that matplotlib does no longer work.
Perhaps some of the next releases...

Hi there,
I experienced some strange errors when I distributed our application to=
some colleagues in Denmark.
The application uses:
Python 2.4
wxPython 2.5.5.1
numeric 23.7
matplotlib 0.83.1
The GUI was designed with Boa Constructor 0.4.4. The exe-file was compi=
led
with py2exe 0.6.3
A student who works for me has made an .exe-file of the application tha=
t
worked fine on our PC's in Norway (I tested it on around 10 PC's, both
Windows XP and 2000). Last week we had a meeting with some colleagues f=
rom
Denmark who brought their laptops and installed the application.
Installation went fine for all of them, but the application would not r=
un
on 3 out of 9 laptops (both Windows XP and 2000).
I understand that the error has something to do with matplotlib and wit=
h
Unicode displaying the letter '=E6', but I can't find out what the reas=
on is
for this. Strange thing is, we use the same letter here in Norway. My g=
uess
i that it has someting to do with language settings on these 3 PC's, bu=
t I
am not sure about this.
Anyone an idea what went wrong here? Thanks a lot in advance!
Oliver

Try deleting the "build" directory and then rebuilding matplotlib. If that
doesn't work then delete the matplotlib directory in python/site-packages.
Hopefully I'll be able to get this working soon.

Mr. Kienzle,
 I just updated my matplotlib from the CVS repository. However when I =
do "import pylab", it igves me different errors depending on what =
directory I am in. If I do it in the matplotlib directory I get the =
error "cannot import name rcParams, verbose" while in any other =
directory I just get the error "cannot import name verbose". Do you know =
what the problem is? Also, in the matplotlib directory the error comes =
from the file numerix/__init__.py, while in the other directories the =
error comes from the file cm.py.
Finally, is there an equivalent of "make clean" for distutils? Meaning, =
if I want to get rid of all the object files and recreate them to see if =
that works, how do I do that? Or is the only way to do that to remove =
the whole matplotlib directory and re-download from CVS?
Hopefully I'll be able to get this working soon.
By the way, when I do get it working do you want me to submit the patch =
for axes.py, or did you already do that?
