python plot axis label code example

Example 1: set axis labels python

# Basic syntax:
plt.xlabel("X axis label") # Add ", fontsize = #" to control fontsize
plt.ylabel("Y axis label")

# Example usage:
plt.plot(range(5))
plt.xlabel("X axis label")
plt.ylabel("Y axis label")
plt.title("Figure title", fontsize = 20)

# 	abbreviation for this, e.g. import matplotlib.pyplot as plt
