New EmonCMS install shows Dial values but no graphs data

I have two Emoncms installations, both on Pi 3Bs and both running SSDs in place of SD cards.
My older unit works fine and I’ve seen no problems. My newly built unit however receives data over USB serial from a local emonTx and displays the changing data on dashboard dials. I have been unable to get any graph data displayed at all and I’m at a loss of what to look for so any help would be much appreciated.
The newer install was built by installing the latest Pi OS the I used the script route to install Emoncms. All appears to be working apart from the graphs. I can’t see any logs full of errors. I’m not sure how to check for SQL database errors - perhaps the data isn’t being logged?
All of my inputs are set to log to feeds and the feed data is updating. I have tried deleting a feed and an input and rebuilding but I still get no graph data (either on realtime visualisations or the graphs tab)

Solved - So I found the problem. The new build is at a remote site that doesn’t have internet access and the date & time were not set correctly so it was acquiring data and saving it based on it’s local date & time whereas the web page uses the local PC time so no data appears.
