Allow historical data to show on the graph when connecting to services like Fitbit.
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.
