Dear Expert,
 Recently after up-gradation of matplotlib and ubuntu 16.04 I am getting transparent figure axis when using the "linux color scheme" option in ipython qtconsole. May I know if there is a way to fix this issue?. I wanted to keep black screen as it reduces eye strain.
ipython qtconsole --matplotlib inline
If I save the image i am able to get axis properly but to see on screen as the axis is not plotted with white background the black axis line and labels are not visible. Earlier I used to get figures as attached in second figure.

Folks,
During the sprints at SciPy Mike Droettboom and I started to adapt the
Jupyter governance documents for matplotlib.
We are doing this in the open, and a pull request of the changes is at:
https://github.com/matplotlib/governance/pull/1
To be clear, this is a work in progress and is not final or in force.
We propose the mechanism for ratifying the these documents is to, after
input from the community, have the current "matplotlib Executive Committee"
(the signers of the FSA with NUMFocus) vote.

Dear all matplotlib users,
I am trying to make a geographical map with colors, in which the colors of
pixels will depend on 2-dimensions of (x,y), like the one attached from one
publication. I searched online and this is where I arrive:
https://gist.github.com/ChaoYue/81eb01b558f068f11ee741c56557a6a2
To put it short, I know how to pick up color by x-axis value, and use
y-axis value as an indicator of either saturation, or brightness or
transparency of the color. Or somewhere to convert this (x,y) information
back to linear space and select color from a matplotlib colormap. But is
there some way that I can use different colors for each corner of the small
square as shown in the example, and somewhere interpolate the colors in
between? like the one attached?
These are the online sources that help me, even though I am not sure I
fully understand the tricks inside them ...:

https://github.com/matplotlib/matplotlib/issues/4369
Thanks a lot in advance for any suggestions,
Cheers,
Chao

scatter does not (currently) support multiple markers in a single call.
You will have to do the group-by operation and call scatter is a loop.
If you define your cmap and norm outside of scatter, you can pass the same
instances into both calls to scatter to have mpl take care of that level of
mapping for you.

OK, after posting I realize I can pass a vector to the 's' keyword in
plt.scatter to set the marker size, like s=[20,20,20,20,20,50,20,20,20,20].
How about using a different marker type? Thanks!

Dear all matplotlib users,
I have a user case that, let's say I have three series data: x,y,z.
I would like to make a scatter plot using (x,y) as coordinates and z as the
color of scatter points, using cmap keyword of plt.scatter. However, I
would like to highlight some specific point by using a different marker (or
marker size) than other points.
​A minimum example is like below:
x,y,z = np.random.randn(3,10)
plt.scatter(x,y,c=z,cmap=matplotlib.cm.jet)
plt.colorbar()​
​If I want to use a different marker or marker size for (x[5],y[5],z[5]),
how could I do that?
The only way I can think of is to plot again for this point using
plt.scatter([x[5],y[5]) but define the color by manually finding the
colormap ​color corresponding to z[5]. However this is quite tedious. Is
there a better way?
​Thanks a lot for any help,
Regards,
Chao​

I originally posted to Stack Overflow at
http://stackoverflow.com/q/38274681/2988730.
I am trying to follow the answer at
http://stackoverflow.com/a/38008501/2988730 to an earlier question of
mine to create colored and styled legend-like entries. I have the
following code:
 import matplotlib as mpl
 mpl.use('ps')
 from matplotlib import pyplot as plt
 mpl.rc('text', usetex=True)
 mpl.rc('text.latex', preamble='\\usepackage{color}\n\\usepackage{dashrule}')
 plt.ion()
 ax = plt.plot((0, 1), (1, 2))[0].axes
 ax.set_ylabel(r'Y $\;$ \textcolor[rgb]{1.0, 0.0,
0.0}{\hdashrule[0.5ex]{3cm}{1pt}{1pt 0pt}}')
 ax.set_xlabel(r'N $\;$ \textcolor[rgb]{0.0, 1.0,
0.0}{\rule[0.5ex]{3cm}{1pt}}')
 plt.savefig('test.ps')
The result is as expected. The labels contain black text with a red
line on the Y label and a green line on the X label:
http://i.stack.imgur.com/JCiLI.png.
However, when I try the exact same set of commands without the
`mpl.use('ps')` line (using `'qt4agg'` backend on my system), the
figure neither saves corectly nor shows up correctly on screen:
 import matplotlib as mpl
 from matplotlib import pyplot as plt
 mpl.rc('text', usetex=True)
 mpl.rc('text.latex', preamble='\\usepackage{color}\n\\usepackage{dashrule}')
 plt.ion()
 ax = plt.plot((0, 1), (1, 2))[0].axes
 ax.set_ylabel(r'Y $\;$ \textcolor[rgb]{1.0, 0.0,
0.0}{\hdashrule[0.5ex]{3cm}{1pt}{1pt 0pt}}')
 ax.set_xlabel(r'N $\;$ \textcolor[rgb]{0.0, 1.0,
0.0}{\rule[0.5ex]{3cm}{1pt}}')
 plt.savefig('test.png')
 plt.show()
The result of `plt.savefig` (http://i.stack.imgur.com/h2LXn.png) and
`plt.show` (http://i.stack.imgur.com/0Ow7c.png) are basically the same
in this case. The lines after the text show up black.
How do I get the colors to show up in the labels with the default
interactive backend?
Regards,
 -Joe

Hi there,
I have been subscribed to matplotlib-users before. I have a new job, and
now I'm connecting from a new email address. I've been using Matplotlib
since before 1.0 was released. Currently, I'm using MPL 1.4.2 and Python
3.5 on Ubuntu Linux 15.04 (if any of that matters).
Please have a look at the following graph:
[image: Inline image 1]
The values in the data set used to plot these two graphs range from 14942
to 14948. In other words, the median of the data set is very far from
zero, but the range of the data is very small. With such a data set, MPL
subtracts a large offset value from the data points, choosing a value such
that the remaining differences are small, positive numbers. I understand
the logic behind this, it simplifies graph labeling on the x-axis of the
left graph, and the y-axis of the right graph.
However, I do not like the way that MPL is displaying the offset value. It
is written in small text, and it does not show up in a consistent place.
On a figure with many adjacent axes, it sometimes isn't clear which axes
owns the annotation. I would prefer to incorporate the offset in the axes
title: for example, the title of the left graph could read "internal
thermistor (+14940)".
So, what is this offset value called in Matplotlib? How do I retrieve it?
How can I override its display? I can obviously do this by wrapping these
particular plots in functions which apply the offset before giving the data
to MPL. But I would prefer to work with MPL itself, as I don't always know
when MPL will judge that a data offset value is needed.
Thanks for your help!

By the way does this:
python -m pip install --upgrade pip # upgrade to latest pip
pip install -f https://nipy.bic.berkeley.edu/manylinux -U matplotlib
work for you to install matplotlib 1.5.1?
Or this, to install 2.0 pre-release?
python -m pip install --upgrade pip # upgrade to latest pip
pip install -f https://nipy.bic.berkeley.edu/manylinux -U --pre matplotlib
Best,
Matthew

Alan,
This mailing list is obsolete; please use mat...@py....
Your traceback looks vaguely familiar as something that has come up 
before, but I don't have any more recollection than that. Suggestions:
1) Install your python environment the easy way via anaconda or 
miniconda: https://www.continuum.io/downloads
2) If you are *sure* you don't want to do it that way, make sure you 
have the most recent version of pip.
3) Likewise, install the most recent matplotlib. See attached message.

Hi there,
I am not the admin so I have installed my own python 3.5.1 and I am using
pip3 to install all modules I need. I got all but matplotlib :-(
pip3 install -U matplotlib

Hello,
consider a case when I want to draw a patch, but it is important how the
border is drawn. For example, if I have an aerial photo and I would like
to add a rectangle of given dimensions as a reference. Having the
rectangle interior white and its border thick and black is good, because
 it ensures that the reference will be always clearly visible,
regardless of whether the photo is dark or bright.
However, as the border is thick, it may significantly overlap with the
interior, which is highly unwanted, because it will look smaller.
Therefore, in this case, I would like to draw the border, but all of it
should be outside of the patch primary area.
And I am sure that there are use cases for the opposite situation.
TL;DR: Take a look at the attached picture to see what I have in mind -
I would like to use "outer borders" (red) or "inner borders", or
classical ones, depending on my needs.
Is there a user possibility to influence how the border is drawn? If
not, how difficult would it be to implement this in matplotlib?

python -m pip install --upgrade pip # upgrade pip to latest
pip install --pre matplotlib
Should now work on all platforms.

You should now be able to get this release on OSX or Linux with:
python -m pip install --upgrade pip # upgrade pip to latest
pip install --pre matplotlib
Cheers,

Folks,
We tagged the first beta for v2.0.0 tonight. Please check out the new
defaults!
This is tagged as a beta because we anticipate a longer than normal release
cycle. The style changes are substantial and we want to make sure that we
have not crippled any common use cases. The target for the final release
around scipy.
A build of the docs is available at http://matplotlib.org/2.0.0b1
Preview conda packages are available via
conda install -c conda-forge/label/rc -c conda-forge matplotlib
pre-release packages should be on pypi tomorrow.
Brief release notes:
This previews the new default style and many bug-fixes. A full list of
the style changes will be collected for the final release.
In addition to the style change this release includes:
 - overhaul of font handling/text rendering to be faster and clearer
 - many new rcParams
 - Agg based OSX backend
 - optionally deterministic SVGs
 - complete re-write of image handling code
 - simplified color conversion
 - specify colors in the global property cycle via `'C0'`,
 `'C1'`... `'C9'`
 - use the global property cycle more places (bar, stem, scatter)
There is a 'classic' style sheet which reproduces the 1.Y defaults:
 import matplotlib.style as mstyle
 mstyle.use('classic')
A big thank you to everyone who worked on this release.
Tom

Hi Paul,
I tried to get the new colormap suggestion from you but could not get the colormap package. Where can I get it? google search did not took me to the package/
Is it a development package?
 May I know how to use viridis color map with an example plot? 
Below is an example code from the link you send
'''
For each colormap, plot the lightness parameter L* from CIELAB colorspace
along the y axis vs index through the colormap. Colormaps are examined in
categories as in the original matplotlib gallery of colormaps.
'''
from colormaps import cmaps
import numpy as np
import matplotlib.pyplot as plt
from matplotlib import cm
import matplotlib as mpl

 Your
 basemap plot is likely setting the aspect of the axes to
 "equal", so it resizes the plot accordingly.
 Otherwise you'd have a pretty nasty amount of vertical
 distortion.
 When you save
 the figure, using bbox_inches='tight' will trim the

Thank you Paul,
 Thanks for the tips related to margins and also about colormaps. Is there a way to stop the automatic aspect ratio setting ( though it it distors map in present case ) if I wanted to use that for other plots?

Yes, the left hand axis is shrinking in the vertical because it is applying the aspect ratio appropriate for 15 N and the N/S extent of your data. Either make the N/S extent of the map larger; make the left hand column wider; or make the figure shorter.

Your basemap plot is likely setting the aspect of the axes to "equal", so
it resizes the plot accordingly. Otherwise you'd have a pretty nasty amount
of vertical distortion.
When you save the figure, using bbox_inches='tight' will trim the excess
white space from the margins:
fig.savefig('map_and_bars.png', dpi=600, bbox_inches='tight')
Also, you should try the new viridis color map :)
