我们的目标是,以填补两个阵列之间的空间y1
和y2
,类似于matplotlib的fill_between。但是我不想用多边形(例如用hatch='|'
)填充空间,而是只在两个数组的数据点之间绘制垂直线。
import matplotlib.pyplot as plt
import numpy as np
n = 10
y1 = np.random.random(n)
y2 = np.random.random(n) + 1
x1 = np.arange(n)
ax.fill_between(x1, y1, y2, facecolor='w', hatch='|')
如果游戏中有很多行,使用LineCollection可能会很方便。与其他答案类似,但价格较便宜:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection
def draw_lines_between(*, x1=None, x2=None, y1, y2, ax=None, **kwargs):
ax = ax or plt.gca()
x1 = x1 if x1 is not None else np.arange(len(y1))
x2 = x2 if x2 is not None else x1
cl = LineCollection(np.stack((np.c_[x1, x2], np.c_[y1, y2]), axis=2), **kwargs)
ax.add_collection(cl)
return cl
n = 10
y1 = np.random.random(n)
y2 = np.random.random(n) + 1
x = np.arange(n)
color_list = [str(x) for x in np.round(np.linspace(0., 0.8, n), 2)]
fig, ax = plt.subplots()
ax.plot(x, y1, 'r')
ax.plot(x, y2, 'b')
draw_lines_between(ax=ax, x1=x, y1=y1, y2=y2, colors=color_list)
plt.show()
