In this tutorial, we’ll try to understand how to plot a 3D wireframe plot in python.

### What is a wireframe plot?

Wireframe plot takes a grid of values and projects it onto the specified three-dimensional surface, and can make the resulting three-dimensional forms quite easy to visualize.

## 3D wireframe plot using the `matplotlib.Axes.plot_wireframe()`

method

To plot a 3D wireframe plot in Python, use the matplotlib Axes objects `plot_wireframe()`

method. The following is the syntax –

**Basic Syntax:**

Axes.plot_wireframe(X, Y, Z, **kwargs)

**Parameters:**

**Upskill your career right now →**

**X, Y, Z**: Data values.**rcount, ccount**: Maximum number of samples used in each direction.**rstride, cstride**: Downsampling stride in each direction.

For more details about the parameters, refer this.

Now let us understand the usage of the above method with some examples.

### Example 1

import matplotlib.pyplot as plt import numpy as np # defining variables x = np.linspace(-1, 2, 10) y = np.linspace(-1, 2, 10) x, y = np.meshgrid(x, y) z = np.sin(np.sqrt(x ** 2 + y ** 2)) #generating the figure and 3d axes fig = plt.figure(figsize = (6, 6)) ax = plt.axes(projection = '3d') #plotting the 3D wireframe plot ax.plot_wireframe(x, y, z) plt.show()

Output:

The steps followed in the above examples are:

- Import required modules.
- Define the variables.
- Generate the figure and 3d axes.
- Plot the 3D wireframe plot using
`Axes.plot_wireframe`

method.

### Example 2

import matplotlib.pyplot as plt import numpy as np from mpl_toolkits import mplot3d # defining variables x, y, z = mplot3d.axes3d.get_test_data(0.05) #generating the figure and 3d axes fig = plt.figure(figsize = (6, 6)) ax = plt.axes(projection = '3d') #plotting the 3D wireframe plot ax.plot_wireframe(x,y,z, rstride=2,cstride=2,color='green') plt.show()

Output:

The steps followed in the above examples are:

- Import required modules.
- Define the variables. Here we used
`mplot3d`

from the`mpl_toolkits`

module to generate our 3d data. - Generate the figure and 3d axes.
- Plot the 3D wireframe plot using
`Axes.plot_wireframe`

method.

### Example 3

You can customize the wireframe plot with additional parameters to the `plot_wireframe()`

function.

**Upskill your career right now →**

import matplotlib.pyplot as plt import numpy as np # defining variables x = np.outer(np.linspace(-2, 4, 8), np.ones(8)) y = x.copy().T z = np.cos(x ** 3 + y ** 4) #generating the figure and 3d axes fig = plt.figure(figsize = (6, 6)) ax = plt.axes(projection = '3d') #plotting the 3D wireframe plot ax.plot_wireframe(x, y, z, edgecolor ='orange') plt.show()

Output:

The steps followed in the above examples are:

- Import required modules.
- Define the variables.
- Generate the figure and 3d axes.
- Plot the 3D wireframe plot using
`Axes.plot_wireframe`

method and pass an additional parameter for the`edgecolor`

.

### Example 4

You can also modify the viewing angle of the wireframe plot.

import matplotlib.pyplot as plt import numpy as np # defining variables x = np.outer(np.linspace(-2, 4, 8), np.ones(8)) y = x.copy().T z = np.cos(x ** 3 + y ** 4) #generating the figure and 3d axes fig = plt.figure(figsize = (6, 6)) ax = plt.axes(projection = '3d') #plotting the 3D wireframe plot ax.plot_wireframe(x, y, z, edgecolor ='orange') ax.view_init(70, 60) plt.show()

Output:

The steps followed in the above examples are:

- Import required modules.
- Define the variables.
- Generate the figure and 3d axes.
- Plot the 3D wireframe plot using
`Axes.plot_wireframe`

method. - Change the view angle by using
`Axes.view_init`

method (refer this).

### Example 5

You can also add a contour plot at the base of a wireframe plot.

import matplotlib.pyplot as plt import numpy as np # defining variables X = np.linspace(-6, 6, 10) Y = np.linspace(-6, 6, 10) x,y = np.meshgrid(X,Y) z = np.sin(np.sqrt(x ** 2 + y ** 2)) #generating the figure and 3d axes fig = plt.figure(figsize = (6, 6)) ax = plt.axes(projection = '3d') #plotting the 3D wireframe plot ax.plot_wireframe(x, y, z) ax.contourf(x,y,z) # ax.view_init(70,60) plt.show()

Output:

The steps followed in the above examples are:

- Import required modules.
- Define the variables.
- Generate the figure and 3d axes.
- Plot the 3D wireframe plot using
`Axes.plot_wireframe`

method. - Plot the 2D contour plot using
`Axes.contourf`

method. - Change the view angle by using
`Axes.view_init`

method (refer this).
