How do I remove the Y-axis from a Pylab-generated picture?

To remove the Y-axis from a Pylab-generated picture, we can get the current axis of the plot and use the set_visible(False) method.

Steps

• Set the figure size and adjust the padding between and around the subplots.

• Create x and y data points using numpy.

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

• Get the current axis of the current figure.

• Set the visibility to False for the Y-axis.

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

Example

import numpy as np
import pylab

# Set the figure size
pylab.rcParams["figure.figsize"] = [7.50, 3.50]
pylab.rcParams["figure.autolayout"] = True

# Random data points
x = np.random.rand(10)
y = np.random.rand(10)

# Plot the data points
pylab.plot(x, y)

# Get the current axis
ax = pylab.gca()

# Set Y-axis visibility to False
ax.yaxis.set_visible(False)

# Display the plot
pylab.show()

Output

It will produce the following output −
