Python matplotlib:使用填充来制作彩色三角形

Python matplotlib:使用填充来制作彩色三角形,python,matplotlib,Python,Matplotlib,我用下面的代码在空间中绘制了随机三角形,但我想用颜色填充这些三角形。我知道matplotlib中的fill\u between()函数,但是我不知道如何在下面的示例中实现它 import matplotlib.pyplot as plt trianglex = [ 1, 10, 7, 1 ] #repeated last coordinates so that the last coordinate joins the first coordinate to form the outline

我用下面的代码在空间中绘制了随机三角形,但我想用颜色填充这些三角形。我知道matplotlib中的
fill\u between()
函数,但是我不知道如何在下面的示例中实现它

import matplotlib.pyplot as plt

trianglex = [ 1, 10, 7, 1 ] #repeated last coordinates so that the last coordinate joins the first coordinate to form the outline of the triangle
triangley = [ 2, 8, 4, 2 ]

triangle2x = [ 13, 25, 21, 13]
triangle2y = [ 5,  7 , 14, 5 ]


plt.figure('Triangles')
for i in range(3):
    plt.plot( trianglex, triangley, 'o-')

for i in range(3):
    plt.plot( triangle2x, triangle2y, 'o-')

plt.show()

这使得您可以使用
plt.fill()
如下所示:

import matplotlib.pyplot as plt

trianglex = [ 1, 10, 7, 1 ] 
triangley = [ 2, 8, 4, 2 ]    
triangle2x = [ 13, 25, 21, 13]
triangle2y = [ 5,  7 , 14, 5 ]

plt.figure('Triangles')
for i in range(3):
    plt.plot(trianglex, triangley, 'o-')
plt.fill(trianglex, triangley)

for i in range(3):
    plt.plot( triangle2x, triangle2y, 'o-')
plt.fill(triangle2x, triangle2y)

plt.show()
输出
