使用matplotlib绘制3D图形

Question

im ysing python 3.7 and i tried to creat a 3d graph but i cant see the graph . this is my code :

    from mpl_toolkits.mplot3d import axes3d
    fig=matplotlib.pyplot.figure()#creating a figure
    chart=fig.add_subplot(1,1,1,projection="3d")
    X,Y,Z=[1,2,3,4,5,6,7,8],[2,5,3,8,9,5,6,1],[3,6,2,7,5,4,5,6]
    chart.plot_wireframe(X,Y,Z)
    matplotlib.pyplot.show()

thanks :)

Answer 1

Not sure what exactly you want to plot, but the z component of a wireframe must be two dimensional:

this shows a plot:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d
import numpy as np

fig = plt.figure()
chart = fig.add_subplot(1,1,1,projection="3d")
X, Y, Z = np.array([[1, 2, 3, 4, 5, 6, 7, 8], 
                    [2 ,5 ,3 ,8 ,9 ,5 ,6 ,1], 
                    np.array([[1, 2, 3, 4, 5, 6, 7, 8], [3, 6, 2, 7, 5, 4, 5, 6]])])
chart.plot_wireframe(X, Y, Z)
plt.show()

If instead, you wanted to plot a curve:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d
import numpy as np

fig = plt.figure()
chart = fig.add_subplot(1,1,1,projection="3d")
X, Y, Z = np.array([[1, 2, 3, 4, 5, 6, 7, 8], 
                    [2 ,5 ,3 ,8 ,9 ,5 ,6 ,1], 
                    [3, 6, 2, 7, 5, 4, 5, 6]])
chart.plot(X, Y, Z)
plt.show()
