In this tutorial, we cover how to make a wire frame / plane graph in Matplotlib. For this, we're just going to use the sample data provided by Matplotlib and leave it there. This type of graph is very specific in its application. If you happen to have your own data, feel free to substitute!
The below code covers an example. I have included the commented out function that generates test data for this, in case you are curious:
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np
'''
def get_test_data(delta=0.05):
from matplotlib.mlab import bivariate_normal
x = y = np.arange(-3.0, 3.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1)
Z = Z2 - Z1
X = X * 10
Y = Y * 10
Z = Z * 500
return X, Y, Z
'''
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x, y, z = axes3d.get_test_data(0.05)
ax.plot_wireframe(x,y,z, rstride=2, cstride=2)
plt.show()
Not going to cover it officially, but check out:
