Thanks for the suggestions. At a quick glance, grafana looks to be perfect for the visualization aspect (at least in terms of capabilities). Glad to see there are free utilities for that and I might not have to resort to chicken scratch html/pyplot :-) I have yet to dig into influxDB still…

Deterrent is right. That graph is terrifying! I feel their frustration regarding getting data from Android apps. Part of what got me started thinking about this was when I realized that the years of data I entered into my fitness pal was suddenly locked behind a subscription service :-( Thanks for sharing!
