Graph Data Query

[tadder]

I am feeding Cumulus with a W-8681, but currently do not run it overnight. When I fire up in the morning Cumulus appears to download Archive records correctly (currently "Archive records read: 30").
Now I think I am correct in that "Graphs" only ever uses data received since Cumulus was fired up, so immediately on start there is no meaningful data to display, this improves the longer Cumulus is running but will never reflect a full day unless the software is running throughout the day. If this is the case, everything is OK. Min/Max covers the period 03/12/2011 - 01/12/2019 but I assume this is another issue?

So on to "Select-A-Graph". No matter what Start - End date I enter there appears to be no data available (I have tried both 'Clear' and 'Update'). All Time Records, Average and Extremes for March, and the year appear OK. Averages and Extremes for Selected period is showing a blank, maybe this is a pointer?

If it helps diagnosis, I have attached a zip of all my Data file.

Any assistance very much appreciated.

The graphs normally would be pre-filled with data from the logs at start up, but: http://wiki.sandaysoft.com/a/FAQ#When_I ... rlier_data

You have a problem with the date formats in your data files; it looks like you have been using Excel or something similar to edit them, and the dates are now in the format dd/mm/yyyy when they need to be dd/mm/yy.

Thank you Steve, you are of course correct. We had a windy day around the 11th and along with many other forum members, I started to get spurious rain data due to mast movement. My attempts to remove this data resulted in the inadvertent format change. I think I must give series consideration to remounting the rain gauge in a more stable position.

I have edited the offending files, and everything appears to be hunky dory.

Cheers
