Thanks very much for the new python script. It works.
The other three files looked great as well.
They were all for Tucson, AZ, USA

yes, definitely looks like there is no data.
I have attached another version of mine, in which the trend line is
disabled by default, but I suspect that would just delay the
inevitable and it would crash trying to do the plot.
I also fixed up a few plotting errors in my code to do with the
mysteries (to me) of layer ordering.
I also had a background bar showing either side of expected arrival -
in this version I have now changed that to start at the expected
arrival and stop 1 hour later.

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]

```
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.

* as you get closer to the equator, tidal changes
dominate the baseline in that timescale - I tried
higher order polynomials, but they are next to useless.
I also had little luck with higher order polynomials to remove
the general trend.
I've put the script here:
