# 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)
# Note, xlabel and ylabel come from matplotlib.pyplot and plt is an
# abbreviation for this, e.g. import matplotlib.pyplot as plt
