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

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.

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.

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.

Thx for help
lo

This is the same behavior that I see. The window resizes horisontally 
when
the pointer is inside the window, although the window behaves 
erratically as
it resizes. Moving the pointer to the right will cause the window to 
grow then
reduce size as you go further right. As soon as the pointer leaves 
the window
the resizing stops. And it only happens while the window is in focus.

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.

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.

The mingw/2.4 build still works. There are instructions at the top of
the setupext.py file. The dll linking error you are getting is
something we ran into a lot. If you have numpy installed distutils
will use the numpy\distutils\mingw32ccompiler.py file. In the
Mingw32CCompiler class remove all links to "msvcr71". In my version
of numpy just comment out the whole if block at line 127.

This error used to come up with mingw and python2.4 builds, but now we
use Visual Studio for python2.4. I am surprised no one else has
reported this error though? I see you used the egg binary? Has
anyone else use the python2.4 windows egg with success.

More information on this bug: on my WinXP laptop, it seems to only 
manifest under some circumstances. When running the script from inside 
SciTE or ipython, it seems more or less repeatable (sometimes it won't 
show on the first run but does from then on), but if the .py file is run 
directly from the windows explorer, it doesn't show up. On my win98 
desktop, however, it shows up regardless.

I also see this behavior in the qtagg and qt4agg backends.

I see weird behaviour like this in Windows too. In my case, the 
horizontal size of the plot window increases as the pointer is moved 
inside a plot region. i.e. the aspect ratio of the window changes 
erratically, I think between two sizes. Sometimes it remains at the 
incorrect shape when the mouse pointer is shifted outside the plot area 
and sometimes it pops back to the correct shape. Is this the behaviour 
you see? I don't know how to avoid it. I noticed that shifting the 
pointer out of the plot area by moving through the bottom of the window 
seems to avoid the possibility of the window remaining with the 
incorrect aspect. I seem to remember seeing this behaviour on an old 
version of matplotlib. I thought it disappeared and has perhaps 
returned. My memory is hazy on this.

I am trying to run Matplotlib 0.87.4 on WinXP after having installed from
the binaries posted on sourceforge. Unfortunately, when I try importing from
pylab, I get a popup declaring:
"This application has failed to start because MSVCP71.dll was not found."
I usually work on Mac/Linux, so I have no idea what this means. Here is the
traceback.

I have tried building matplotlib myself using mingw32, but with no success.
Any help is most appreciated.

I am using matplotlib to display a couple of fits-images and then use
the mouse to select a source in the image. However, when I click on
the window containing the image to get it into focus the window starts
resizing itself based on the movement of the mouse. I am on a mac
with OS 10.4 and are using TkAgg. Has anyone seen this before and
know how to avoid it from happening?
Cheers

Joseph,
I'm a big fan of masked arrays in numpy. Your problem is typically what masked 
days are for: you can find an example here:

 From what I see matplotlib is just connecting points. Just because 
your x values have what you think are gaps, matplotlib doesn't know 
that. I assume your two calls to plot use the x and y values for each 
plot. Matplotlib will connect points that are sequential no matter what 
the x values are. There may be ways to assign the y values as NANs for 
those "missing" x values.

The way I do that is index the time data and plot against the index.

Thanks to all who replied.
I am not sure if I get this or if I am not clear on what I want. So I
am attaching a simple web page of what I want vs. what I get from
matplotlib.
Thanks again,
Joseph

matplotlib doesn't make any assumptions about whether data is
continuous or not. It only knows about points and line styles. If
you want a set of points to be connected, use a linestyle like '-'
(solid line) or '--' (dashed line)
 plot(x, y, '-')
if you don't want the points to be connected, use a marker like 'o'
for circles and 's' for squares
 plot(x, y, 's')
You will need to extract the subsets of the data that you want
connected yourself. 
JDH

Yes,
I am plotting two lines and am using two plots, the two lines plots just
fine in different colors, however, one line is continuous from 1983 -
1995 and the other dataset has irregular data points along the same
period of time. So I should see a continuous line for the first data
set and I should see a broken line only where there is data for the
second. Matplotlib is joining the broken points and forces both
datasets to appear as continuous.

What do you think is the solution?

Hi, I'm also new to matplotlib, but this sounds like a general type of
problem you might in find in matlab too. I think you are trying to plot
two separate lines, one for the first set of time and one for the second
set of time. If you don't want them connected then you must issue two
plot() commands, which means you have to split the data into the
sections that you want connected.

I have a question (new user here): I have datasets of irregular time
spaced data and am having a problem with Matplot lib.
=20
I am plotting two datasets: one is continuous time series data (simple
line chart) and the other irregular time series data.
=20
The problem I have is: MatPlotLib is interpolating data for the
irregular data where there is no data.
=20
So if I have data from 1985 - 1989 then no data for 1990 - 1994,
matplotlib is drawing a line connecting the missing data.

How does one plot irregular spaced time series data?
