Vega color names

Nelle Varoquaux
Hello everyone,

Nathan just proposed names for the new vega colors:
https://github.com/matplotlib/matplotlib/issues/7248

As Antony mentioned, getting the names right is quite important as
this is probably going to be the default for the next 10 years.

Cheers,
N

PyQt4 in Matplotlib v2.0.0

Ray Osborn
I just created a new conda environment with Matplotlib included, and it duly installed matplotlib: 2.0.0-np111py27_0. It installed PyQt5 by default, whereas I need PyQt4, but when I installed PyQt4 (conda install pyqt=4), it automatically downgraded Matplotlib to 1.5.1.
--------
The following packages will be DOWNGRADED due to dependency conflicts:

    matplotlib: 2.0.0-np111py27_0 --> 1.5.1-np111py27_0
    pyqt:       5.6.0-py27_2      --> 4.11.4-py27_4    
    qt:         5.6.2-0           --> 4.8.7-4
--------
Is PyQt5 really a dependency for Matplotlib v2? I have been testing release candidate versions of Matplotlib v2 without any problem. This will cause headaches to my users who want the latest features.

Re: PyQt4 in Matplotlib v2.0.0

Benjamin Root
no, pyqt5 is not a dependency for matplotlib. this looks like a conda packaging issue.

Side note: the sourceforge mailing list is deprecated. Please use the python.org version instead (you'll have to re-register).

Re: PyQt4 in Matplotlib v2.0.0

Paul Hobson-2
It appears that the build of matplotlib in conda-forge does not require pyqt5:

So in your case, I would do:

conda remove pyqt5 matplotlib
conda install --channel=conda-forge matplotlib
