Ah, now it makes sense. My script to collect the data runs via cron which ensures the script only ones once at DST change, so I am missing the data point for 01:00 BST (rather, my loader script assumes the entry for 01:00 on the 25th Oct is GMT so there is nothing inserted. I've fixed in now based on this - I allow a 7200 second gap which allows the graph to continue uninterrupted. Thanks for your help on this!
