Interval component not updating as input but as event


#1

If I use the dcc.Interval component as an Input('id', 'n_intervals') for my callbacks, it doesn’t update on appstart and only triggers at some point later on (my guess is, when one of the other inputs for the callback gets triggered), but as an Event('id', 'interval') it works just fine right away. What am I missing?

Concerning this issue: The problem seemed to be that I returned “None” to other graph elements within the app when they were supposed to be empty. For some reason this stopped all graphs from working. Is this intended? Is there a proper none-value one should pass to a Graph that should remain empty? I basically returned them a dummy graph with one datapoint.
