Comment:
1. show method of a graph doesn't do anything now. There is a line missing
in the code.
2. 2 doctests are still failing (see [comment:42 Comment 42])
'''Questions.'''
A. Sorry to ask this question, but why is figsize not an option for `plot`
again?
B. If I understand correctly,
- `DEFAULT_SHOW_OPTIONS` will affect `g.show()`.
- `DEFAULT_PLOT_OPTIONS` will affect `g.plot()`.
but
- `DEFAULT_SHOW_OPTIONS` will not affect `g.plot()`.
- `DEFAULT_PLOT_OPTIONS` will affect `g.show()`.
Right?
'''Comments.'''
C. This works:
{{{
sage: sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['edge_color']='red'
sage: g = graphs.PetersenGraph()
sage: g.plot() # red edges
sage: g.show() # does not show anything
sage: g = Graph({3:[4,5]})
sage: g.plot() # red edges
sage: g.show() # does not show anything
}}}
D. This is now ok:
{{{
sage: g = graphs.PetersenGraph()
sage: p = g.graphplot()
sage: p.plot(my_favorite_useless_option_I_always_used_in_my_code=45)
/Users/slabbe/Applications/sage-5.6.rc0/local/bin/sage-ipython:1:
DeprecationWarning: This method takes no argument ! You may want to give
it as an argument to graphplot instead.
