<p>You can use the proper typesetting Unicode minus (see

<a class="reference external" href="https://en.wikipedia.org/wiki/Plus_sign#Plus_sign">https://en.wikipedia.org/wiki/Plus_sign#Plus_sign</a>) or the ASCII hyphen

for minus, which some people prefer. The matplotlibrc param

axes.unicode_minus controls the default behavior.</p>

<p>The default is to use the Unicode minus.</p>
