How to show minor tick labels on a log-scale with Matplotlib?

To show minor tick labels on a log-scale with Matplotlib, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.
  • Create x and y data points using numpy.
  • Plot x and y data points using plot() method
  • Get the current axis using gca() method.
  • Set the yscale with log class by name.
  • Change the appearance of ticks and tick label using ick_params() method.
  • Set the minor axis formatter with format strings to format the tick.
  • To display the figure, use show() method.


import numpy as np
import matplotlib.pyplot as plt
from matplotlib.ticker import FormatStrFormatter

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

x = np.linspace(-2, 2, 10)
y = np.exp(x)

plt.plot(x, y)

ax = plt.gca()

plt.tick_params(axis='y', which='minor')
