Comment (by paulmasson):
The `@rename_keyword` decorator in this file first appeared in #4201. On
the same ticket this decorator and `@options` were added to
`misc/decorators.py`. The description for the latter is about the
convenience of the end user, so I think we can assume the same for the
former.
The functions in a plot get passed to `line.py` as subplots, and the
`_allowed_options` for lines include `rgbcolor` but not `color`. We can't
just rename keywords here that are expected to have a certain name
elsewhere, unless you want to track down every plot file that will get
output from `plot.py` and change all of them.
What Travis had me do in #9654 was raise the `ValueError` only if both
keywords were used at the same time. This lets the end user input either
keyword as desired but avoids conflicting information that might confuse.
On #9654 color values were passed to another keyword, so I did the check
to make sure only one was present and set the new keyword value. For this
ticket `rgbcolor` is expected in other places, so after checking that only
one is present you could use presumably use the function
`rename_keyword(color='rgbcolor')` when `color` is present to copy over
values, but then always use the keyword `rgbcolor` when passing values
elsewhere.
This reply is bit long-winded, but I'd like to have a record of some of
the details of how plotting works in Sage. Let me also know if I've not
yet been clear enough.
