带有刻度的路径效果的线条#
可以使用 TickedStroke 沿着线条添加刻度，以将一侧标记为障碍。您可以控制刻度的角度、间距和长度。
刻度也会在图例中正确显示。
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import patheffects
# Plot a straight diagonal line with ticked style path
fig, ax = plt.subplots(figsize=(6, 6))
ax.plot([0, 1], [0, 1], label="Line",
path_effects=[patheffects.withTickedStroke(spacing=7, angle=135)])
# Plot a curved line with ticked style path
nx = 101
x = np.linspace(0.0, 1.0, nx)
y = 0.3*np.sin(x*8) + 0.4
ax.plot(x, y, label="Curve", path_effects=[patheffects.withTickedStroke()])
ax.legend()
plt.show()
