Hi,
I have been trying to set up a custom color cycle in matplotlib using the
matplotlibrc file. I have encountered a problem with the default
matplotlibrc file provided with the installation from Arch llinux's package
manager and the example provided in the online documentation at:
https://matplotlib.org/users/customizing.html
When the lines controlling the axes.prop_cycle are uncommented:
axes.prop_cycle : cycler('color',
['1f77b4', 'ff7f0e', '2ca02c', 'd62728',
'9467bd', '8c564b', 'e377c2', '7f7f7f',
'bcbd22', '17becf'])
the following message is generated when I import matplotlib:
/usr/lib/python3.6/site-packages/matplotlib/__init__.py:1078: UserWarning:
Illegal line #338
" ['1f77b4', 'ff7f0e', '2ca02c', 'd62728',

Key axes.prop_cycle: 'cycler('color',' is not a valid cycler
construction: unexpected EOF while parsing (<string>, line 1)
(val, error_details, msg))
The same error is generated if I import cycler using
import cycler
or
from cycler import cycler
I am using matplotlib 2.0.2 in python version 3.6.2 installed from the Arch
Linux repositories.
The ouput of uname -a is :Linux tinker 4.12.12-1-ARCH #1 SMP PREEMPT Sun
Sep 10 09:41:14 CEST 2017 x86_64 GNU/Linux
To reproduce:
Copy the default matplotlibrc
Uncomment the lines containing
axes.prop_cycle : cycler('color',
['1f77b4', 'ff7f0e', '2ca02c', 'd62728',
'9467bd', '8c564b', 'e377c2', '7f7f7f',
'bcbd22', '17becf'])
Run python in the directory containing the matplotlibrc file
Import matplotlib
Am I missing something obvious?
Thanks,
Emlyn
