Tp append a single labeled tick to X-axis using matplotlib, we can take the following steps.
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.
Set xticks at a single point.
Set the tick label for single tick point.
To display the figure, use Show() method.
Example
import numpy as np
import matplotlib.pyplot as plt
# Set the figure size
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
# Create x and y data points
x = np.linspace(-5, 5, 50)
y = np.sin(x)
# Plot x and y data points
fig, ax = plt.subplots(1, 1)
p = ax.plot(x, y)
# Set xticks at a point
ax.set_xticks([-1.075])
# Set xticklabels for the point
ax.set_xticklabels(["$\\bf{It\ is -\!1.075\ label}$"])
# Display the plot
plt.show()
Output
It will produce the following output −
