Create Multiple Axes in Matplotlib

In this tutorial of the Matplotlib, we will look at a short introduction about axes instances and see how to add multiple axes instances to a figure with the help of the add_axes() method in Matplotlib.

Create Multiple Axes With the `add_axes()` Method in Matplotlib

To add an axis or multiple axes instance in Matplotlib, use the `add_axes()` method. We need to assign them to a region within the figure when adding axes.

We specify the coordinates of its lower-left corner and its size and the coordinates in the `add_axes()` method. The range should be 0 to 1, and we also specify width and height proportional rather than absolute.

Let’s start by importing all the modules required.

``````import matplotlib.pyplot as plot
import numpy as np
import matplotlib as mpl
``````

We create a figure, and the `figsize` is 8 by 6 inches. Set its background color to yellow using the `facecolor` argument.

``````figure=plot.figure(figsize=(8,6),facecolor="yellow")
``````

Add the three-axes instances using the `add_axes()` method. The method accepts a tuple to define orientation.

The first parameter is the coordinate `x`, the second `y` coordinate, the third `width` and the fourth is the `height`. We will also set the `facecolor` as `'cyan'`.

``````axes1=figure.add_axes((.1,.1,.5,.4),facecolor='cyan')
``````

We define the `x` and `y` values. We will use some functions from the `numpy` library.

``````x1=np.linspace(.10,10,100)
y1=10 * np.sin(x1)
``````

Now, we display the plot for three instances of axes. The parameters `x1`, `y1` and `color` as `"navy"`.

``````axes1.plot(x1,y1,color="navy")
axes2.plot(x1,y1,color="navy")
axes3.plot(x1,y1,color="navy")
``````

Full Source Code:

``````import matplotlib.pyplot as plot
import numpy as np
import matplotlib as mpl

figure=plot.figure(figsize=(8,6),facecolor="yellow")

x1=np.linspace(.10,10,100)
y1=10 * np.sin(x1)

axes1.plot(x1,y1,color="navy")
axes2.plot(x1,y1,color="navy")
axes3.plot(x1,y1,color="navy")
plot.show()
``````

We’ll get a figure with three-axis instances. In this figure, we can view all coordinate points with corresponding axes.
