import matplotlib.pyplot as plt

import pydarn

fitacf_file = "20190831.C0.cly.fitacf"
darn_read = pydarn.SuperDARNRead(fitacf_file)
fitacf_data = darn_read.read_fitacf()

pydarn.RTP.plot_summary(fitacf_data, beam_num=2,
                        range_estimation=pydarn.RangeEstimation.TIME_OF_FLIGHT)
plt.show()

This also needs some changes in the rtp.py module too for the axes and stuff to make sense. Maybe a line in fan.py that stops the plot from using this range estimate?

(Let me know if you want me to sort that out)

Otherwise everything works!

If you would like to sort that out I would appreciate it, I am less familiar with where RangeEstimations are all used! Thanks
