Unicode minus
=============

You can use the proper typesetting `Unicode minus`__ or the ASCII hyphen for
minus, which some people prefer. :rc:`axes.unicode_minus` controls the default
behavior.
By default, tick labels at negative values are rendered using a `Unicode
minus`__ (U+2212) rather than an ASCII hyphen (U+002D). This can be controlled
by setting :rc:`axes.unicode_minus` (which defaults to True).

"It can be controlled by setting the rcParam (meaning, to either value)"?

I think it is fine the way it is.

The default is to use the Unicode minus.
This example showcases the difference between the two glyphs.
