Hi

Looking at the select a graph for May 14th I have a peak rain total of over 80mm at around 18:00 but the dayfile only show 2.1 for the day. Odd ! I guess the dayfile has rejected an extreme but not the graph.

Regards

Alan

The figure that goes into dayfile.txt is simply the total at the end of the day (because under normal circumstances with a correctly behaving station that would be the peak value), so presumably your total went down again after that erroneous value?

Note that select-a-graph gets its data from the monthly log file, so that's where your erroneous figure is coming from, if you want to correct it.
