[英]matplotlib “rotate” gradient
I have this code that display a triangle filled with a gradient. 我有这段代码显示填充有渐变的三角形。
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
X, Y = np.meshgrid(np.linspace(0,1), np.linspace(0,1))
Z = 1.-X-Y
Z[Z<0] = 0
cset = ax.contourf(X, Y, Z, zdir='x', levels=np.linspace(0,1),offset=0, cmap=plt.cm.jet)
ax.set_xlabel('X')
ax.set_xlim(0, 1)
ax.set_ylabel('Y')
ax.set_ylim(0,1)
ax.set_zlabel('Z')
ax.set_zlim(0,1)
plt.show()
How can I have the gradient "slices" in the other "direction"? 如何在另一个“方向”上设置渐变“切片”? I mean, the gradient should look like this:
我的意思是,渐变应如下所示:
The answer to this question has already been given here: 这个问题的答案已经在这里给出:
Fill a triangle in 3D matplolib plot with a color gradient 用颜色渐变填充3D Matplolib图中的三角形
where I show two ways of producing a gradient fill in a 3D triangle using contourf
and plot_surface
. 在这里,我展示了两种使用
contourf
和plot_surface
在3D三角形中生成渐变填充的方法。
