On the matter of the full 24 hour graph on the daily view: that has been complained about here on the message boards for a while ā¦ a few times by me. The management does not seem to officially recognize the problem, so Iām not confidant if it is on the action plan ā¦ maybe just down near the bottom 
You say you are missing the most recent 4 hours, but my observation (on 15 second data) was that 8-9 most recent hours was missing from the Cayenne App. But today I look at it, and I get 8 hours from 24 hours ago, and then 16 hours are missing. Perhaps it is different in different circumstances ???
My solution was to write my own app from the CaySimple library. Here is what I see on a data source that updates a Cayenne series every 15 seconds with a HHMM.SS number, which should run from 0 to 2359.59. As you can see, the Cayenne App gives me 8 hours from yesterday morning, then 16 hours missing, but the homemade App gives the full 24 hour cycle, with the midnight reset.
