matplotlibで日本語を使う(japanize-matplotlib)

Posted at

記事について

matplotlibで日本語を使おうとすると文字化けして不便
japanize-matplotlibというライブラリが便利そう
https://pypi.org/project/japanize-matplotlib/

使い方

通常のmatplotlib

import matplotlib.pyplot as plt

plt.plot([1, 2, 3, 4])
plt.xlabel('簡単なグラフ')

plt.show()

Figure_1.png

文字化けしてしまう。

パッケージをインストール

pip install japanize-matplotlib

インポートして普通にmatplotlibで描画

import matplotlib.pyplot as plt
import japanize_matplotlib

plt.plot([1, 2, 3, 4])
plt.xlabel('簡単なグラフ')
plt.show()

Figure_1.png

日本語が文字化けせずに描画できて便利。
