> Just FYI, #8082 added correct plotting of complex points. Perhaps the
input documentation needs to be updated, but there is an example in the
documentation of it being used. Note also #9982 and #4838.
Unfortunately, neither #8082 nor #4348 adds any documentation about
plotting complex numbers directly via points. Plotting them via `plot` or
`list_plot` is of course well documented. Also, it appears #4348 is
incomplete; it does not work with single complex numbers.
{{{#!python
sage: from sage.plot.plot import xydata_from_point_list
sage: xydata_from_point_list(CC(I))
([0.0], [1.0])
sage: xydata_from_point_list([CC(I), CC(1)])
([0.0, 1.0], [1.0, 0.0])
sage: xydata_from_point_list([CC(I)]
([0.0], [1.0])
}}}
Since the patch here does not break the code which deals with more than
one instance of complex numbers, I suggest that we proceed with the
patches here and deal with complex numbers in `point` or `line` in #9982.
The following ''undocumented'' behavior is broken with this ticket
{{{
plot(CC(I))
}}}
but the following works
{{{
plot([CC(I)])
plot([CC(I), CC(1)])
}}}
