matplotlib-users Mailing List for matplotlib (Page 3)

For my part, I didn't take Keith's comment as antagonizing. If anything, I
should apologize to Sandro. It was not necessary for me to drag Debian into
this, because all I know is that I was having issues on Ubuntu.

We do support ubuntu, travis.ci (which we use for continuous integration
testing) is ubuntu based and my main development box is ubuntu (but I
mostly work inside conda environments rather than virtualenvs these days).
Even though it is the worst thing for a dev to say, 'it works on my
machine'.
Part of the problem here is that it looks like you are doing system-wide
installations from source so you have almost certainly driven your system
into an inconsistent state. Unless you know enough sys-admin magic to
ensure you won't step on the toes of the system packages, I strongly
suggest _never_ using sudo to install python packages. Either use
venv/conda or install into a directory in your home directory and modify
$PYTHONPATH as needed.
 I know it is frustrating, but there isn't a whole lot we can do to help
you with you knowing exactly what you have done to your system.
In any case antagonizing the developers and the debian packager is _not_
the most effective course of action. I assure you all of us are making a
good faith effort to make sure mpl works everywhere. Starting from that
assumption will make all of these conversations go much more smoothly.
Also remember everyone responding to you on this list is a volunteer,
please be respectful of our time and energy.

An important question that I should have asked before. Exactly where did
you get the installer from? That might help us figure out what happened
here.
As for a workaround, if you want to get savy with the command-line, you
could run "pip install six" on the command-line. That should install it for
you, and then you can try installing matplotlib through the executable.

We would too. This is the first time I have seen updating setuptools not
work. That was the fix... I have no clue why it is broken on your system.

One thing I just noticed is that python3.4 and the distutils libraries are
installed at /usr/lib/python3.4/distutils/, but the setuptools is located
at /usr/local/lib/python3.4/dist-packages/. One of the oddities of
setuptools is that it monkey-patches distutils, if I understand it
correctly, so perhaps it isn't doing it correctly for some reason? I
haven't a clue, really.
This oddity in directory structures was actually one thing I noticed in
Ubuntu last summer/fall for py2.7 that broke a lot of things for me. I was
in a rush at the time, so I just switched to anaconda, nuked everything
python in my .local and moved on. That is always an option here, but it
would be nice to get to the bottom of this as well.

I did as you suggest and got the "No module named matplot lib" message. I
installed version 1.4.3 and got the "no module named six" message. I then
deleted all the matplotlib files once again and installed version 1.3.1 and now
my matplotlib program runs. Is there something else could try?

Chances are, there is some sort of mixup in your installs (as evidenced by
the failure to go back to the previous version). I would try uninstalling
all matplotlib installs, then checking to see if python still sees
matplotlib anywhere (by running the script). It *should* say "No module
named matplotlib" or some such. Once all of that is removed, install
matplotlib again.

You need to install the six module, no matter which version of Python you use.

I downloaded version 1.4.3 and installed it (i.e., executed 
matplotlib-1.4.3.win32-py2.6.exe). Now when I
attempt to run a program I get the following:
>python rainfallYears.py
Traceback (most recent call last):
 File "rainfallYears.py", line 4, in <module>
 import matplotlib.pyplot as plt
 File "C:\Python26\lib\site-packages\matplotlib\__init__.py", line 105, in
<module>
 import six
ImportError: No module named six
>Exit code: 1
So then I went back to 1.3.1 and get the same error...
Help!

I'm confused is corrplot a matplotlib function? If it's not, there's not much we can do. You should probably just modify it to accept axes as parameters.

 Hi Paul,
         I could not succeed in
 plotting corrplot.Corrplot(df,ax=ax1).
 
 infact the plotting procedure is
 c=corrplot.Corrplot(df,ax=ax1)
 then issue command
 c.plot().
 So there are 2 steps involved, which may be the
 complication. I am not very well versed with Matplotlib.
 Kindly help.

 All the
 
 pandas plots that I've used take an axes keyword so
 try:
 
 c =
 corrplot.Corrplot(df, ax=ax1)
 
 
 or
 c =

 Do either of those

I guess to do so you would have to plot each line independently. I don't 
know about anything in mpl that could do that with just your data passed 
to the function.
You could look for an other library based on mpl, or write one yourself 
I guess.
Sorry to not be of any more help with this

Hello all,
I am trying to make Grotrian diagrams using matplotlib.
For those who don't know about grotrian diagrams here's the link(
http://en.wikipedia.org/wiki/Grotrian_diagram)
They essentially depict transitions between different energy levels of the
atoms.
Currently I have the data regarding the different energy levels of the
various atoms and need matplotlib to get the grotrian diagram of the atom
upon supplying it with the energy level data.
Can anyone please help me with this?
Regards,
Amol

Brenton,
It's good to know that those other solutions work. Unfortunately, I'm just
sitting down at my Windows 7 computer, and I can't reproduce your problem.
I'm also using the Anaconda Python distribution, which might have different
behavior than your installation method.
However, you're in luck, because there are many, many ways to get IPython
to do what you want. (In fact, anything the Python interpreter does,
IPython does better.) All the possible options, though, can make things a
little tricky... Here's a couple of examples:
C:\> ipython -i filename.py
That will start IPython and automatically load the Python file "filename".
That way anything you define in "filename" will be available in the new
IPython session. Alternatively, you can use the IPython "%run" magic from
inside an IPython session:
In [1]: %run filename.py
That has the same effect as the first example.
As an alternative, IPython notebooks (
http://ipython.org/ipython-doc/stable/notebook/notebook.html) are a very
nice way to interactively work with some data while also retaining all of
the analysis code in a script-like manner. You can have your plots
displayed in the webpage by typing the following in one of the cells:
import matplotlib.pyplot as plt
%matplotlib inline
You can install this using pip:
C:\> pip install ipython[all]
I'm sorry I couldn't help you with your original problem, but I hope these
suggestions help.

Sorry Brenton, I meant for my reply to go to the entire list.
Anyway, in your response, I take it that you meant to say that the window
appears and disappears immediately. Yes?
What happens if you restart the Python interpreter and type the following?
>>> import matplotlib
>>> matplotlib.use('TkAgg')
>>> import matplotlib.pyplot as plt
>>> plt.plot([1,2,3])
>>> plt.show()
Does my first example work fine in the IPython interpreter? (Sorry, I'm not
on my Windows machine right now, so I can't tell you if I'm seeing the same
problem.)

Sorry,
 I tried both ax= and axes= both did not work. before testing I thought it is the correct way but did not work some how.

Hi,
I am on Windows 7 64 bit SP1 and I installed matplotlib via wheels files 
here http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib but now 
whenever I execute plotting commands from the python shell (e.g., the 
'hi mom' example here 
http://matplotlib.org/1.4.3/users/shell.html?highlight=mailing%20list#other-python-interpreters) 
it seems like as though some window is trying to pop up but nothing 
does. Whereas if I try the the hist example here 
(http://matplotlib.org/1.4.3/users/shell.html?highlight=mailing%20list#ipython-to-the-rescue) 
in IPython I get a graph pop-up that seems fine.

Thank you Paul,
 I could not follow fully what you meant by that in reply. but below is the info available with corrplot.
Kindly provide some help.
With best regards,
Sudheer
 Here are some examples provided that the data is created and pass to c::
 | 
 | c = corrplot.Corrplor(dataframe)
 | c.plot(cmap=('Orange', 'white', 'green'))
 | c.plot(method='circle')
 | c.plot(colorbar=False, shrink=.8, upper='circle' )

Hello,
I'm trying to learn if there is a better or less tedious way of changing the
x-axis time scale interval size when plotting time series data using
MATPLOTLIB.
To account for all the different x-axis intervals that I may end up using, I
usually do the following imports:
from matplotlib.dates import YearLocator, MonthLocator, WeekdayLocator,
DateFormatter, DayLocator
from matplotlib.dates import MO, TU, WE, TH, FR, SA, SU
Then I specify specific intervals by doing the following:
year = YearLocator()
month = MonthLocator(bymonth=range(1,13), bymonthday=1, interval=1)
week = WeekdayLocator(byweekday=MO) # Every MOnday
day = DayLocator(bymonthday=range(1,32), interval=1)
Then apply any of the above formats by doing:
axes.xaxis.set_major_locator(year)
axes.xaxis.set_major_locator(month)
I find all that above too tedious since I may then decide to change the
intervals to something different to experiment.
With R's ggplot2 or Yhat's ggplot, it is very simple and intuitive to change
the x-axis scale interval. You just need to specify the breaks and
minor_breaks interval like so:
scale_x_datetime(labels=date_format("%Y-%m"), breaks="3 months",
minor_breaks="1 month")
I've quit using MATPLOTLIB for plotting time series data because of this. 
However, I thought perhaps there is a better way that I am not aware of.
If there is a better way, please educate me! Thanks!

Okay. I figured out the problem. You need to pass a dictionary to the
config magic. Here is the relevant code:
%config InlineBackend.print_figure_kwargs = {'bbox_inches':None}
I created a PR with IPython (https://github.com/ipython/ipython/pull/8051)
to add this information to the %matplotlib documentation, so this doesn't
cause confusion for others.
Thanks to all the IPython and MPL devs for these great tools!

Thanks Tom.
Your hint led me to the following page:
https://github.com/ipython/ipython/blob/aab20bf85126f5b1da857193c446aebe6346acec/docs/source/whatsnew/version2.0.rst#other-changes
So it seems that this change is quite old, and I never noticed it before...
The suggestion on that page requires some incantation of the %config magic.
I tried this:
%config InlineBackend.print_figure_kwargs.bbox_inches = None
Which silently passes, but doesn't change the behavior.
Your rational for IPython's use of this kwarg by default is sound, and I
understand that there are valid use cases for it in some circumstances.
However, I still think this is problematic. I like MPL because you can make
a plot to your exact specifications -- but setting this kind of behavior by
default (without a well documented fix) feels a little "Microsoft
Office"-y... That being said, I really don't care all that much. IPython is
a fantastic tool. I'll just move my plotting code to a separate script and
tweak things there. (But then I won't be able to share the notebook with my
fancy plot embedded except as an external image. Can't have everything.)
I actually don't want any sort of 'tight' layout; however, just for
reference, the `tight_layout` function throws an error in my example.
