I've connected Beeminder to my Fitbit account and am experimenting with tracking a few things. One behaviour is frustrating though: • Beeminder imports historical data from Fitbit (I'm not sure whether it's all data or just a fixed prior period as I've not had my Fitbit for more than 10 days)
• But… the graph begins only the day before

Since the data has been imported, I would like it to show on the graph, thus providing me with some visual "momentum". Else, why bother importing it?

Of course, if all historical data is imported and someone has been using a service for a very long time, then that might make for a very heavy graph before the official goal even begins. The solution there is to allow us to nominate the date on which the goal begins, for a period of up to, say, 14 days earlier.
