Tp append a single labeled tick to X-axis using matplotlib, we can take the following steps.

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(["$\bf{It\ is -\!1.075\ label}$"])
