How to plot single data with two Y-axes (two units) in Matplotlib?
To plot single data with two Y-Axes (Two units) in Matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create speed and acceleration data points using numpy.
- Add a subplot to the current figure.
- Plot speed data points using plot() method.
- Create a twin Axes sharing the X-axis.
- Plot acceleration data point using plot() method.
- Place a legend on the figure.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True speed = np.array([3, 1, 2, 0, 5]) acceleration = np.array([6, 5, 7, 1, 5]) ax1 = plt.subplot() l1, = ax1.plot(speed, color='red') ax2 = ax1.twinx() l2, = ax2.plot(acceleration, color='orange') plt.legend([l1, l2], ["speed", "acceleration"]) plt.show()
