I have experimented the setupext.py a little bit and find this change can compile matplotlib using MacPorts python and Tcl/Tk without conflict: def parse_tcl_config(self, tcl_lib_dir, tk_lib_dir): ... tcl_poss = [tcl_lib_dir, os.path.normpath(os.path.join(tcl_lib_dir, '..')), "/usr/lib/tcl" + str(Tkinter.TclVersion), "/opt/local/lib"] # /usr/lib is replaced by /opt/local/lib tk_poss = [tk_lib_dir, os.path.normpath(os.path.join(tk_lib_dir, '..')), "/usr/lib/tk" + str(Tkinter.TkVersion), "/opt/local/lib"] # /usr/lib is replaced by /opt/local/lib ... I also replaced this logical statement: elif sys.platform == 'darwin': by elif sys.platform == 'dummy': The reason why I replaced /usr/lib with /opt/local/lib instead of expanding the tcl_poss and tk_poss lists is that the system tclConfig.sh and tkConfig.sh are located in /usr/lib, while the MacPorts tclConfig.sh and tkConfig.sh are located in /opt/local/lib. I don't think we really need specially treatment for Mac OS, since tclConfig.sh and tkConfig.sh will return correctly Tcl/Tk lib/include path. Maybe I am missing something? I have tested this and it works perfectly fine. Surely this assumes the MacPorts Tcl/Tk are installed. Conditions need to be added so they can check wether we are using MacPorts Python, wether MacPorts Tcl/Tk exist if using MacPorts Python. If MacPorts Tcl/Tk exist then we use /opt/local/lib, otherwise we use /usr/lib. Hope this helps. Thanks.

Michael Droettboom-3 wrote > I have created https://github.com/matplotlib/matplotlib/issues/2025 to > track this. Hi Michael, thanks. I am somewhat convinced the problem is related to matplotlib 1.3.x, not the Tk library. I tried on Linux that uses Tk8.5 and I got the missing ticks for inverted log axes as well. So the TkAgg backend only works properly with matplotlib 1.2.0. I further tested macports python, matplotlib 1.3.x and system Tk 8.5 on Mac. I did so by uninstalling macports version of Tk/Tcl (8.6). The ticks are also missing. Additional test on gtkagg backend shows the same thing: matplotlib 1.2.0 works perfectly fine with gtkagg, while matplotlib 1.3.x has the missing ticks. Probably you have a better sense on what is going on? -- View this message in context: http://matplotlib.1069221.n5.nabble.com/missing-ticks-on-inverted-log-axis-tp41063p41095.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.

Yes, I can confirm the system Python doesn't work with TkAgg and
matplotlib 1.3.x. The problem with matplotlib 1.3.x and Macports Python
is that the Tk/Tcl library used in setupext.py is hardwired to system Tk/Tcl
for Mac platform. Here is the piece of code from setupext.py:
elif sys.platform == 'darwin':
# this config section lifted directly from Imaging - thanks to
# the effbot!
# First test for a MacOSX/darwin framework install
from os.path import join, exists
framework_dirs = [
join(os.getenv('HOME'), '/Library/Frameworks'),
'/Library/Frameworks',
'/System/Library/Frameworks/',
]
Therefore matplotlib 1.3.x is compiled with system Tk/Tcl regardless which
python is used (macports or system). I have tried to hardwire the macports
Tk dynamic library but there are errors when importing matplotlib in python.
It would be great if the devs can modify the setupext.py to use macports
Tk/Tcl
libraries properly, e.g., enabling a choice for using system or macports
Tk/Tcl
libraries.

I guess I will just modify the codes in "tri" package so I can use them as
standalone modules.
Thanks.

Re: [Matplotlib-users] missing ticks on inverted log axis
I find the issue came from the matplotlib backend. The problem is gone when using TkAgg backend. However, TkAgg doesn't work with matplotlib 1.3.x, which has some conflict of Tk dynamic library due to different Tk version, i.e., macports uses Tk8.6 and Mac OSX 10.8.3 uses Tk8.5. I really need the "tri" package in matplotlib 1.3.x. Is there anyway I can manually replace the "tri" package in matplotlib 1.2.0 (installed by macports) with the one in matplotlib 1.3.x (downloaded from the latest master in github repository?

I am using np version 1.7.1 and matplotlib version 1.3.x. In fact I have the same problem with matplotlib version 1.2.1. Could it be the problem with Mac OS (mountain lion 10.8.3)?

[Matplotlib-users] missing ticks on inverted log axis
Hi, I am having troubles to correctly make a figure with inverted log axis.
This is what I am doing:
import numpy as np
import matplotlib.pyplot as plt
y=np.linspace(-90,90,20)
z=np.arange(1,1.e4, 200)
c=y.reshape(20,1)*z.reshape(1,len(z))
fig,ax=plt.subplots()
plt.pcolor(y,z,c.transpose())
ax.set_yscale('log')
ax.invert_yaxis()
The problem is that the ticks of y axis is not displayed correctly once I
invert the y axis. It shows the tick at 1000. All other ticks such as 100,
10 and 1 are missing. Am I doing something wrong or is this a bug in
matplotlib?
Thanks for your help.
