この事例は、Windows10_1909 で Python 3.9.0 環境では、動作しません。( t = ax.text(.... がデグレートしたのか？ )
import matplotlib.pyplot as plt DATA = ((1, 3), (2, 4), (3, 1), (4, 2)) # dash_style = # direction, length, (text)rotation, dashrotation, push # (The parameters are varied to show their effects, # not for visual appeal). dash_style = ( (0, 20, -15, 30, 10), (1, 30, 0, 15, 10), (0, 40, 15, 15, 10), (1, 20, 30, 60, 10), ) fig, ax = plt.subplots() (x, y) = zip(*DATA) ax.plot(x, y, marker='o') for i in range(len(DATA)): (x, y) = DATA[i] (dd, dl, r, dr, dp) = dash_style[i] #print('dashlen call %d' % dl) t = ax.text(x, y, str((x, y)), withdash=True, dashdirection=dd, dashlength=dl, rotation=r, dashrotation=dr, dashpush=dp, ) ax.set_xlim((0.0, 5.0)) ax.set_ylim((0.0, 5.0)) plt.show()

Python 3.11.2 見直しました。上記のコードでは、下記のエラーが発生します。

matplotlib 内部のエラーのようです。matplotlib の改修（先祖帰りバグの改修）を待つしかない。
