"""
Demonstrates plotting multiple linear features with a single ``ax.pole`` call.

The real purpose of this example is to serve as an implicit regression test for
some oddities in the way axes grid lines are handled in matplotlib and
mplstereonet.  A 2-vertex line can sometimes be confused for an axes grid line,
and they need different handling on a stereonet.

import matplotlib.pyplot as plt
import mplstereonet

fig, ax = mplstereonet.subplots(figsize=(7,7))
strike = [200, 250]
dip = [50, 60]
ax.pole(strike, dip, 'go', markersize=10)
ax.grid()
plt.show()


Add two-point example to serve as a regression test for gridline/plot distinguishing
