ざっくり調べた感じ2つ方法がある
1つは japanize-matplotlib を使う方法
三重大学の奥村さんが記事にしてる
https://oku.edu.mie-u.ac.jp/~okumura/python/plot.html
ただし、このパッケージはpipでしかインストールできない
conda-forgeで探したけどない
なのでパス
------------
もう1つは日本語fontを指定する方法
labelに日本語を使いたいときは、
matplotlib.pyplotの日本語化 #Python - Qiita
この記事のコマンドをpython上で走らせると、matplotlibで使える日本語フォントが表示される
自分のMacで実行してみた結果は以下
from matplotlib import font_manager

いっぱい表示されるけど、日本語っぽいのはヒラギノくらいだった
色々と試したけど、Herveticaとヒラギノくらいしか成功しなかった・・・・
これをコードの上の方に書いておけばOK
import matplotlib as mpl
mpl.rc('font', family='Hiragino Sans')
(mpl.rcParams['font.family] のように書いてもいけるらしい)
(自分はなぜかこれを書かなくても日本語が表示されるようになってしまってよくわからないことになった・・・)
または
pylab.ylabel(r"あああああああ",fontsize=30, fontname='Hiragino Sans')
と必要なところだけ書いても良い
labelじゃなくてlegendの場合は、
pylab.legend(loc='upper right', prop={"family" :'Hiragino Sans'})
のように指定する、少し特殊
最近は別のサーバーでjupyter noterbookを立ち上げて使うことがほとんどだから自分にはあまり関係がないけど、Macユーザーの場合は1度書いておけば楽ですね
自分の環境にも ~/.matplotlib というディレクトリはあることは確認
# matplotlibの日本語
macは ~/.matplotlib/matplotlibrc に書いときゃOKcd ~/.matplotlib
echo "font.family : Hiragino sans" >> matplotlibrc
