[英]matplotlib contours labels in 3D
Is there any way to put contours labels in 3D plots? 有什么方法可以在3D图中放置轮廓标签? Clabel is apparently not implemented in 3D
Clabel显然未在3D中实现
import numpy as np
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
x,y = np.meshgrid(np.linspace(-1,1,10),np.linspace(-1,1,10))
z=-(x**2+y**2)
fig,ax = plt.subplots()
C=ax.contour(x,y,z)
ax.clabel(C)
fig = plt.figure()
ax = fig.add_subplot(111,projection='3d')
C=ax.contour(x,y,z,zdir='z',offset=-2)
ax.clabel(C)
As clabel is not implemented and the return value is None, there is indeed no point in calling clabel()
for the time being. 由于未实现clabel且返回值为None,因此暂时没有必要调用
clabel()
。 You can use the C.levels
attribute to manually add labels to the graph . 您可以使用
C.levels
属性将标签手动添加到图形 。
It won't have the nice inline
feature that hides the contour under the labels though. 它不会具有将标签的轮廓隐藏在标签下的漂亮的
inline
功能。
