matplotlib version: 3.8.2 Note testers: please indicate what version of matplotlib you are using

MAKE SURE THE HDW REPO IN utils/hdw CONTAINS THE NEW HDW FILES ON INSTALLATION OF THIS BRANCH

We can plot the FOV for now:

import pydarn
from datetime import datetime
import matplotlib.pyplot as plt 

stids = [51,52,53,54,55,56]
cols = ['salmon','salmon','gold','gold','cornflowerblue','cornflowerblue']
plt.figure(figsize=(8, 8))
rtn=pydarn.Fan.plot_fov(stids[0], datetime(2021, 2, 5, 18, 5),
                        fov_color= cols[0],radar_location=True,
                        radar_label=True, coastline=True)

for i, stid in enumerate(stids[1:]):
    rtn=pydarn.Fan.plot_fov(stid, datetime(2021, 2, 5, 18, 5), ax=rtn['ax'],
                            ccrs=rtn['ccrs'], fov_color= cols[i+1],
                            radar_location=True, radar_label=True,
                            coastline=True)
plt.show()

Which will plot:
