【Python】デバッグ用のグラフ描画関数

Posted at

#背景
Anacondaの商用有償化でVSCodeで実装およびデバッグを行っているが、デバッグ時にグラフを書くためのコードの記述が面倒

#対策
pyplotのimport、グラフの描画、メモリの解放までやってくれる関数を作成する。

#コード

def dbplot(*args):
    import matplotlib.pyplot as plt
    # 可変長引数を一つの文字列に結合する
    argument = ""
    for i,val in enumerate(args):
        if i==0:
            argument += "args[{}]".format(i)
        else:
            argument += ",args[{}]".format(i)
    # 文字列をplotの引数として実行
    exec("plt.plot({})".format(argument))
    # グラフ表示
    plt.show()
    # グラフエリアをクリア
    plt.clf()
    # グラフのメモリ解放
    plt.close()

if __name__ == "__main__":
    # グラフ描画用に適当な配列を準備
    x = [1,2,3,4,5]
    y = [1,2,3,4,5]
    z = [2,4,6,8,10]

    # デバッグ用プロット関数実行
    dbplot(x,y,x,z)
