Odd graph behaviuor

For unexplained reasons my base station lost contact with the FO wh1091 sensor this evening. I jiggled the batteries in the sensor unit and removed/reinserted them in the base station, and things worked again. Not sure the cause although the base display was showing "full memory".

Anyway, when I looked at the graphs after the restart, they showed glitches in pressure, outside temperature and RH. So I stopped Cumulus and edited the file Feb11log.txt. The offending values were immediately obvious so I edited them to more reasonable values. When I rebooted Cumulus, all was well, but one graph, the outside temperature in View > Graphs still showed the glitch. The pressure and RH graphs are clean. The same outside temperature graph in select-a-graph does not show this.

Where is the View > Graphs ->Outside temp stuff being stored or cached?

The outside temperature graph is created at start up from the outside temperature values in the monthly log files (e..g. Feb11log.txt).

Looking at your graph, outside temp looks fine; it's apparent temp and heat index that you have problems with.

Thanks, Steve, you are right. That will teach me to put on my glasses when looking at graphs with fine lines :-)

The good thing is I now know how to fix glitches!
