我已经通过下面的代码在空间中绘制了随机三角形,但是我想填充三角形的颜色。我知道matplotlib中的fill_between()
函数,但是我不确定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()
