Matplotlib - 3D Wireframe Plot



A three-dimensional axes can be created by passing projection='3d' keyword to the axes creation routine. After creating 3D axes, matplotlib.Axes3D.plot_wireframe() function is used to draw wireframe plot.

Syntax

matplotlib.Axes3D.plot_wireframe(X, Y, Z, 
                                 rcount, ccount, 
                                 rstride, cstride)

Parameters

X, Y, Z Required. Specify Data values.
rcount, ccount Optional. Specify maximum number of samples used in each direction. If the input data is larger, it will be downsampled to these numbers of points. Setting a count to zero causes the data to be not sampled in the corresponding direction, producing a 3D line plot rather than a wireframe plot. Defaults to 50.
rstride, cstride Optional. Specify downsampling stride in each direction. These arguments are mutually exclusive with rcount and ccount. If only one of rstride or cstride is set, the other defaults to 1. Setting a stride to zero causes the data to be not sampled in the corresponding direction, producing a 3D line plot rather than a wireframe plot. Default of rcount = ccount = 50.

Example:

In the example below, wireframe plot is drawn for the test data present within the package.

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

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.set_title('Wireframe Plot')

#getting test data
X, Y, Z = axes3d.get_test_data(0.05)

#drawing wireframe plot
cb = ax.plot_wireframe(X, Y, Z, cstride=2,
                          rstride=2, color="green")

plt.show()

The output of the above code will be:

3D Wireframe Plot

Example:

Lets consider one more example. Here, the wireframe plot is drawn from user defined 3D plane.

import matplotlib.pyplot as plt
import numpy as np

def f(x, y):
  return np.sin(np.sqrt(x ** 2 + y ** 2))

xlist = np.linspace(-6.0, 6.0, 100)
ylist = ylist = np.linspace(-6.0, 6.0, 100)
X, Y = np.meshgrid(xlist, ylist)

#creating 3D plane
Z = f(X, Y)

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.set_title('Wireframe Plot')

#drawing wireframe plot
cb = ax.plot_wireframe(X, Y, Z)

plt.show()

The output of the above code will be:
