Hello,
Not being a programmer, I probably shouldn't have messed with this, but
being curious...
I tried the code posted on github as well as the one by Cameron D. In both
cases I got the following error:
```
root@n4mrv:/home/bg/weewx_tonga_browse-main# python3 ./tonga.py [file
from Cameron D]
distance to eruption 12056.6 km arrival at 1642258360 (2022-01-15 09:52:39)
opposite pulse arrival at 1642308921 (2022-01-15 23:55:21)
second time around pulse arrival at 1642385471 (2022-01-16 21:11:10)
Traceback (most recent call last):
File "./tonga.py", line 178, in <module>
plot_burst( cursor, arrival_time, hour_span, "primary" )
File "./tonga.py", line 54, in plot_burst
coeff = np.polyfit(xdata, ydata, background_order )
File "<__array_function__ internals>", line 180, in polyfit
File "/usr/local/lib/python3.8/dist-packages/numpy/lib/polynomial.py",
line 638, in polyfit
raise TypeError("expected non-empty vector for x")
TypeError: expected non-empty vector for x
```
I added my lat/lon information but may have missed something else I need to
change. Python modules were installed as directed. Copy of weewx.sdb is in
the same directory as the program.
Thanks.
Bob
