[Matplotlib-users] linestyle option for FancyArrowPatch and similar commands

[P P. <pp...@gm...>]

Hi all,

   I was wondering why there are inconsistent values for the 'linestyle' 
option in matplotlib.backend_bases.GraphicsContextBase. The values 
allowed are 'solid', 'dashed', 'dotted' and 'dashdot', aside from tuples.

Compare this with the options available for the usual pyplot.plot() 
command, where the linestyles are '-', '--', '-.', ':', etc.

Is there a specific reason for the difference in the options? It doesn't 
seem too hard to add the options '-', '--', etc to the 
GraphicsContextBase class - one only needs to add these to a dict at

https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/backend_bases.py#L671
