我试图隐藏或删除超出“ outer_arc_left”和“ outer_arc_right”的“ outer_rect”部分,以重新创建溜冰场。
谢谢。
from matplotlib.patches import Rectangle, Arc
def draw_rink(ax=None, color='black', lw=2, outer_lines=False):
if ax is None:
ax = plt.gca()
outer_rect = Rectangle((-1500, 3000), 3000, 3000, linewidth=lw, color=color, fill=False)
outer_arc_left = Arc((-700, 5200), 1600, 1600, theta1=90, theta2=180, linewidth=lw, color=color)
outer_arc_right = Arc((700, 5200), 1600, 1600, theta1=0, theta2=90, linewidth=lw, color=color)
rink_elements = [outer_rect, outer_arc_left, outer_arc_right]
for element in rink_elements:
ax.add_patch(element)
return ax
答案 0 :(得分:1)
如果不清楚要隐藏的部分,则很难“隐藏补丁的一部分”。您可以创建路径并将其用作clip_path
,但其作用更像是屏蔽,例如矩形的边缘将被裁剪。定义该路径将是棘手的事情。
但是我们可以反过来:如果仍然需要定义路径,则可以简单地使用该路径作为要显示的形状。
import matplotlib.pyplot as plt
from matplotlib.path import Path
from matplotlib.patches import PathPatch
x = [1,1,1,2,3,4,4,4,1]
y = [0,1,2,2,2,2,1,0,0]
verts = list(zip(x,y))
codes = [1,2,3,3,2,3,3,2,2]
path = Path(verts,codes)
patch = PathPatch(path)
plt.gca().add_patch(patch)
plt.gca().autoscale()
plt.show()
