Re: [Matplotlib-users] problems installing matplotlib on OS X Lion
I had a problem getting with Lion as well. I was able to work around it by:
1) unsuccessfully trying to install matplotlib for python 2.7 via macports
2) then using easy_install to install matplotlib

[Matplotlib-users] problems installing matplotlib on OS X Lion
After many unsuccessful attempts at getting matplotlib installed on OS X Lion,
I ran across this page:
Installing Matplotlib on OS X 10.7 with Homebrew « Random Musings for the
Digital Age
Following these instructions got me the closest I have been:
$ brew install python
$ brew install gfortran
$ brew install pkg-config
$ easy_install pip
$ pip install numpy
$ cd $HOME
$ git clone https://github.com/matplotlib/matplotlib.git
$ cd matplotlib
$ python setup.py build
$ python setup.py install
At the moment, I'm trying to get a script that was working on EPD 7.1 to work
on Python 2.7.2. I'm using the TkAgg backend.
The first messages I see when running the script are:
objc[68962]: Class TKApplication is implemented in both
/Library/Frameworks/Tk.framework/Versions/8.5/Tk and
/Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used.
Which one is undefined.
objc[68962]: Class TKMenu is implemented in both
/Library/Frameworks/Tk.framework/Versions/8.5/Tk and
/Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used.
Which one is undefined.
objc[68962]: Class TKContentView is implemented in both
/Library/Frameworks/Tk.framework/Versions/8.5/Tk and
/Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used.
Which one is undefined.
objc[68962]: Class TKWindow is implemented in both
/Library/Frameworks/Tk.framework/Versions/8.5/Tk and
/Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used.
Which one is undefined.
For both Tk and Tcl, ../Versions/Current points to 8.6.
From there, everything is fine until it executes show(), when I get the
following messages:
Exception in Tkinter callback
Traceback (most recent call last):
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py",

line 236, in resize
self.show()

line 240, in draw

File

line 19, in blit
tk.call("PyAggImagePhoto", photoimage, id(aggimage), colormode,
id(bbox_array))
TclError
Can anyone suggest how to resolve this problem?
Thanks,

I don't think he's describing a histogram, because he is not plotting
frequency of observations on the y axis, but data values (means of
each bin). I think what surfcast23 wants is just a bar graph.
So, surfcast23, I'd suggest you break it down into your two steps.
First, how will you average your values by bin? You can probably
figure that out by writing it out on paper in pseudo-code and then
just putting it in Python. Then you'll have a list of means, and you
will pass that to the bar function in matplotlib, something like:
from pylab import *
ax = subplot(111)
x = arange(4)
your_list_of_means = [4,5,7,11] #computed earlier
bar(x, your_list_of_means)
xticks( x + 0.5, ('Bin1', 'Bin2', 'Bin3', 'Bin4') )
show()

So you do want a histogram then? I assume you have all of this sorted then, the histogram function is very good.

Re: [Matplotlib-users] How do you Plot data generated by a python script?
Hi Martin, Sorry I am just responding. I have been busy getting ready for the semester. What I need to do is first sort the values contained in the column and assign them to bins. I then have to plot the number of bins by the mean value in each bin. mdekauwe wrote: > > Can you describe what you want to do?
