Can I display historical heart rate data (e.g., my heart rate for the last month or year)? I can display my heart rate data for one day by choosing Health Stats > Heart Rate (and can use the "<" and ">" arrows to move between days), but this only displays one day at a time. My Fitbit shows my heart rate for the last 30 days. (I'd also like to see movement, sleep, etc over time, but the trend of my heart rate is most important to me.)
