The actual choice depends on the device capabilities.
The graph duration may be dependent on the device. If you find that it is different on your watch please send feedback to firstname.lastname@example.org.
There are three presentation options for the graphs (line, area or colors).
Colors is only available on devices with color display.
Color mapping depends on the type of the graph:
HR: according to the sport for which the current activity retrieves heart rate zone thresholds, or ‘generic’ if there is no activity (zone 1 – gray, zone 2 – blue, zone 3 – green, zone 4 – yellow, zone 5 – red)
Body battery: <= 25 – red, <= 50 – yellow, <= 75 – green, <= 100 – blue
