If I remove the span options then it works fine, this is with no span options:
This is with graph_span (different graph colors/labels, I’ve got several to test different options):
This is with:
graph_span: 13h
span:
start: day
Once I add the offset value I get “Loading…”. I’ll repeat the tests after the span interval has passed, but will have to wait another 22 hours for that to happen.
