带有勾选路径效果的行

可以沿线添加刻度以使用 将一侧标记为障碍 TickedStroke。您可以控制刻度的角度、间距和长度。

刻度也将适当地出现在图例中。

# 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()
