Nice work (Morrowwn thanks!). If you have any nulls in the data during the selected timeframe, change the query to read: (Cameron D thanks!)
*query = "select datetime, barometer from archive where datetime > %.0f and datetime < %.0f and barometer is not null order by dateTime;" % (start_time, stop_time)* [image: hunga_tonga.png] If you want the bars closer to the rise and falls of the events, need to adjust the speed of sound slightly.
