How to switch axes in Matplotlib?

MatplotlibPythonData Visualization

To switch axes in matplotlib, we can create a figure and add two subplots using subplots() method. Plot curves, extract x and y data, and set these data in a second plotted curve.


  • Create x and y data points using numpy.

  • Create a figure and add a set of two subplots.

  • Set the title of the plot on both the axes.

  • Plot x and y data points using plot() method.

  • Extract the x and y data points using get_xdata and get_ydata.

  • To switch the axes of the plot, set x_data and y_data of the axis 1 curve to axis 2 curve.

  • Adjust the padding between and around the subplots.

  • To display the figure, use show() method.


import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-2, 2, 50)
y = np.sin(x)
f, axes = plt.subplots(2)
axes[0].set_title("First plot on axis")
curve, = axes[0].plot(x, y, c='r')
newx = curve.get_xdata()
newy = curve.get_ydata()
axes[1].set_title("Switch of first plot")
curve2, = axes[1].plot(x, y, c='r')
