1# Basic syntax:
2plt.axvline(x_coordinate)
3
4# Example usage:
5import matplotlib.pyplot as plt
6plt.figure(figsize=(5, 5))
7plt.axvline(x=10, ymin=0.10, ymax=0.70, color='b', ls='--', lw=1.5, label='axvline - % of full height')
8plt.legend(bbox_to_anchor=(1.0, 1), loc='best')
9plt.show()

11# Where:
12#	- x is the x axis coordinate for the vertical line
13#	- ymin is the minimum y-value to show
14#	- ymax is the maximum y-value to show
15#	- ls is the line style (see also '-', '-.', and ':')
16#	- lw is the line width
