Re: [Matplotlib-users] iregular data set

[Rodrigues, Joseph]

Thank you very much, you are a lifesaver.  I took your advice and found
a working example on the internet
http://www.scipy.org/Cookbook/Matplotlib/Plotting_values_with_masked_arr
ays (saves an image as png when run)

Made some minor modifications and it worked perfectly.

Thank you very much.

I tried commenting out that very block, but then numpy will not build
-- it does not see the mingw32 compiler without those lines, it
appears. I used the --compiler switch on the build, but to no avail.

I'm a bit stuck here, as matplotlib does not build, and the binary
does not seem to work. I'm trying to put together a package that
contains numpy, matplotlib and scipy to distribute to some of my
users.

Re: [Matplotlib-users] Weird resizing issue

[Tommy Grav]

This is the same behavior that I see. The window resizes horisontally whenthe pointer is inside the window, although the window behaves erratically asit resizes. Moving the pointer to the right will cause the window to grow thenreduce size as you go further right. As soon as the pointer leaves the windowthe resizing stops. And it only happens while the window is in focus. TommyOn Jul 22, 2006, at 8:59 PM, Gary Ruben wrote:I see weird behaviour like this in Windows too.

[Matplotlib-users] matplotlib/wxmpl/numpy conflict on windows xp: runtime error, C-API ?

[massimo sandal]

Hi,
I'm trying to install a matplotlib+wxmpl app I wrote on Linux on a 
Windows XP machine.


It crashes starting with the following error:
-

I installed the latest sourceforge stable (not CVS/SVN) versions of 
matplotlib, numpy and wxmpl as of today.


I'm quite puzzled, I guess I understand what the error is (different gcc 
versions?), but how can I get around it? Do I need to recompile 
numpy/matplotlib?

Re: [Matplotlib-users] Missing dll in windows build 0.87.4

[Christopher Barker]

msvcr71.dll is a dll required for virtually every application built with 
MSVC7.1. For example, py2exe distributes it by default when it builds 
exes. However, it is so common, most systems already have it, installed 
by some other app.

I'm guessing in this case, you're working with a new Windows box that 
hasn't had much installed on it yet. I don't have it booted up now, but 
I don't have much installed on my Windows box, and I have at least a 
half a dozen copies of it on my system, a few in standard system 
directories.

For completeness, I guess that dll should be included in the egg. In the 
  meantime, search your system for it, I bet you have at least one copy. 
If not, I'll bet you can get it from MS's web site.

Now that I think about it, I'm surprised it isn't distributed with 
Python in the first place. Someone with a Windows box should do a search 
and see where they are, and if there is one with Python.

-Chris

The missing DLL in this case is

  "This application has failed to start because MSVCP71.dll was not found."

which I believe is the C++ runtime.

Not really.  I am using Visual Studio for the build in which I have
never seen or heard of this error occuring.  This was a mingw problem,
and the fix I mentioned was what we did when the builds were done with
mingw.

We got this error no matter what.  I had the file all over the place
and the mingw builds still complained.

I am guessing you installed numpy1.0b1.  You need to use 0.9.8.

You need the tk devel headers -- do you have tk.h?  Is it in your
include path?

Is this related to the pointer coordinates shown in the lower-right
corner of the window? I.e., when you move the pointer right, perhaps
the x-coordinate becomes a longer number and the window is enlarged to
accommodate it. I remember seeing behavior like this on some old
version of Matplotlib (probably TkAgg backend on OS X) but cannot
reproduce it now.

That looks like the problem. If you click the zoom widget in qt4agg, 
then "zoom to rect mode" also appears on that line, forcing the width of the 
window to increase even further.

Hence my suspicion that this was a dll that is not included in Stock 
Windows, but is on most people's systems, installed by other software. I 
think the OP said s/he was a new (or infrequent) Windows user.

didn't the OP get this error with a MSVC build?

Anyway, I don't have windows booted to test myself, and I'm out of my depth.
