[Matplotlib-users] Europe without coastline
Hello,
This weekend I started using matplotlib and I think it is great.
Beautiful graphs with very little effort.
My data is geographical so I would like to draw on a map, North-Sea (UK
- Netherlands). For this I installed the basemap on my Debian system
(Stable/Wheezy). This has a strange problem. If I zoom out, all is
there. If I start zooming in coastlines disappears. Is this my
mistake, a problem in the packages in Debian, or something else?
Thanks

Hi,
I am using mat 1.20 and basemap 1.0.5, I tried your code and don't have the
same issue.

Re: [Matplotlib-users] ANN: matplotlib 1.3.0 released
Yes, I mean a self-built package. When linking I think setupext.py is using /usr/lib and /usr/local/lib first, instead it should use PKG_CONFIG_PATH and then /usr/lib and then /usr/local/lib.

Re: [Matplotlib-users] 1.3.0 and py2exe regression
I have little to no experience with py2exe, so I don't know how much I
can help there.
However, between 1.2.1 and 1.3.0, mpl_toolkits was changed to a
namespace package, which allowed basemap to install into it despite it
coming from matplotlib (and being installed with setuptools). I don't
know if that has any bearing on py2exe.

results in ImportError: No module named mpl_toolkits

running from mpl_toolkits.axes_grid import make_axes_locatable, axes_size
itself in python works fine.
I've built a machine afresh and am getting this. Also, it seems to build
fine on win amd64 - but as that is my main development machine, there may be
some polution there
options={'py2exe': {'packages' : ['matplotlib', 'mpl_toolkits', ...
I've tried various different permutations of the above in includes with no
success.
Can anybody suggest why this is failing in 1.3.0 when it is working in 1.2.1
?

I don't think PKG_CONFIG_PATH is supposed to have anything to do with linking directories. PKG_CONFIG_PATH tells pkg-config where to look for .pc files, which *in turn*, by querying pkg-config, may contain information about link directories. So when you say it should prepend PKG_CONFIG_PATH, do you mean it should prepend what pkg-config returns? I think that probably what it should be doing, and it's a bonafide bug that it is not. Any chance you can share the linker command line that you think is wrong, and how it needs to be re-ordered?

Re: [Matplotlib-users] 1.3.0 and py2exe regression
Thanks, for the moment, it seems that removing the 'mpl_toolkits' from packages makes it work. Also, with the removal of dateutil from the binary, and installation of dateutil from source pulling in six via easy_install/pip meant it also was not found by py2exe. I got around this by using Christoph Gohlke's binary installer of six. HTH someone else.

[Matplotlib-users] Animation of a scatter plot with a large number of points
Good afternoon. I have a list of 2 points with coordinates x,y and category in three lists. x_coordinate=[3000,3100,3234,.] x_coordinate=[15678,16768,14590,.] category=[1,3,5,] The categories values are between [1 and 10] I need to make a 2D animation of this in matplotlib, starting showing the first element and finalizing showing all elements in the graph, showing the color points cording to the category. I tried modifying the example of animatedScatter, but I can see that the number of points in the scatter plot is constant from the beginning. is there any way to make the program, for example show in the first time step one element one point in the second time step, two points, etc? and also one important thing is could cop with a big list of points with the minimum lag of time in the animation?

[Matplotlib-users] Importing pyplot blocks input thread
I am trying to write some code that uses an input thread to check for user
input while another thread is running some calculations (see example below).
What I have noticed is that just including an import of pyplot (regardless
of whether it is used by the code or not) causes the call to raw_input in
the input thread to block the main thread. It works fine when I don't
import pyplot. Importing pyplot is a consequence of other libraries that I
need to use in the code, so I would like to find a way to make this work.
I have python 2.7.3, matplotlib 1.2.0, and am currently using the GTKAgg
backend. Any help is much appreciated.
Here is the example code:
import time
import threading
import matplotlib.pyplot # Works fine if this is commented out
def input_thread():
raw_input('Press a key:')
print Input data received
thread = threading.Thread(target=input_thread)
thread.start()
time.sleep(.01)
print
# Main thread (e.g. a calculation that can take some time)
for i in xrange(10):
print i
time.sleep(.5)

Re: [Matplotlib-users] Importing pyplot blocks input thread
On 2013/08/06 10:08 AM, John McFarland wrote:
I am trying to write some code that uses an input thread to check for user
input while another thread is running some calculations (see example below).
What I have noticed is that just including an import of pyplot (regardless
of whether it is used by the code or not) causes the call to raw_input in
the input thread to block the main thread. It works fine when I don't
import pyplot. Importing pyplot is a consequence of other libraries that I
need to use in the code, so I would like to find a way to make this work.
I have python 2.7.3, matplotlib 1.2.0, and am currently using the GTKAgg
backend. Any help is much appreciated.
Here is the example code:
import time
import threading
Before the *first* import of pyplot, you need to have:
import matplotlib
matplotlib.use(agg)
or specify any other non-interactive backend. Alternatively, you can
specify the backend in a matplotlibrc file.
This assumes you don't actually need an interactive backend. If you do
need it, then I suspect you will need to change the strategy you are
using in your program, ideally eliminating the input thread. You might
use a gtk idle event callback to handle the user input, for example.
The problem here is that python threads and gui toolkits tend not to mix
well.
I suspect that raw_input is using the PyOS_InputHook, which is also
being used by gtk, so you are violating the prohibition against
gui-related activities being in more than one thread.
Eric
import matplotlib.pyplot # Works fine if this is commented out
def input_thread():
raw_input('Press a key:')
print Input data received
thread = threading.Thread(target=input_thread)
thread.start()
time.sleep(.01)
print
# Main thread (e.g. a calculation that can take some time)
for i in xrange(10):
print i
time.sleep(.5)

Eric Thanks Eric, that did work for me. I don't necessarily need an interactive backend for this, but it could be nice to get it to work. I just tried switching raw_input to sys.stdin.readline, and that seems to work even with the interactive backend.

This on OSX 10.6: Python 2.7.5 just installed from python.org X11 installed from the Apple installation disks for 10.6 before `pip install matplotlib` No homebrew etc Any hints about how I should debug this further? Thanks a lot for any help, Matthew I was able to install numpy 1.7.1 and matplotlib 1.30 under OS X 10.6.8 with X11 version XQuartz 2.3.6 (xorg-server 1.4.2-apple56) and python 2.7.5 64-bit from python.org using pip 1.4. Have you tried running Software Update? If you installed X11 after updating to 10.6.8 you can run the combo updater ( http://support.apple.com/kb/DL1399 ) to get the latest X11. Alternately, you could try installing XQuartz from http://xquartz.macosforge.org/landing/ Yes, the system was up to date before I installed matplotlib. Just to check my failing memory, I checked for updates (none), reinstalled and got the same answer. The combo updater looks like it's a fast track to the same outcome as Software update - is it something different? I don't remember if Software Update detects updates to X11. What version of X11 are you running? The version on the Snow Leopard install disks, 2.3.4, is older than version 2.3.6 installed by the combo updater. Sorry - I am afraid I installed the combo updater over the existing X11 before I read your email properly, so I don't know what version I had before. As far as I know there is no standalone X11 2.3.6 updater for Snow Leopard. You'll have to re-install the security updates that came out after the combo updater was released if you use it, which is a bit of a pain. According to otool -L, the libpng12.0.dylib installed with X11 2.3.6 is version 45, compatibility version 45, so it should work with matplotlib. Yes, that does work thanks. If you don't want to run the combo updater because of possible side effects or install XQuartz you can download libpng from http://sourceforge.net/projects/libpng/files/libpng15/1.5.17/, unpack it and do the standard ./configure, make, sudo make install to install it in /usr/local/lib. setup.py should find it there. So, to summarize, pip install for matplotlib will fail on bare-bones OSX 10.6 unless you do one of: * Run the combo updater * Install Quartz X11 * Build your own libpng in /usr/local Is that a reasonable list? Is there any way to check for this problem and warn / error at build time with instructions? Thanks a lot for the help, Matthew -- Get 100% visibility into Java/.NET code with AppDynamics Lite!
