WMR86 rain graph makes no sense

[dogzodiac]

Just purchased the weather station, but the rain graph puzzles me. For example if an inch of rain falls in an hour it shows an inch on the graph for the first hour, so fine, but after a few hours that inch of rain moves along the line but decreases in value. did some experimenting and in the total 24 hour maximum got the total up to 2inches, but as time went by and before the 24 hours was up the graph hardly showed any total in the 12 or 24 graph lines. so what am i missing

It's the same on the WMR200, there's a thread here somewhere about it. As you say, it makes no sense.
