I’m getting similar results to Dennis with version 9.31a. The trends chart is currently showing a temperature difference of +13F, whereas the 24-hour graph shows a temperature difference of approximately zero from 24 hours ago. Similarly unrealistically large differences in humidity and dew point. See what I mean at http://home.pacbell.net/ian_h/Allison.htm
i have found something in the latest vers that might help
dennis: is you have a ws2000 type station, the glicht with the month data file will be causing this problem
see graph frozen thread
Brian,
Version 9.34d WMR-968
Checking the trend for last 24 hrs is really off:
Today’s current temp is: 19
Yesterday at this time: 17
The trend is showing: -25.5 in the 24 hour column.
Now the temp appears to be more or less OK, but barometer is still off, and humidity is way off. It’s showing -47%, whereas the 24-hour graph is showing a few %.
Temperature, barometer and humidity look OK now, but dew point is still squirrely. My 24-hour graph shows the dew point now is higher than it was 24 hours ago.
