I measure my pulse ox continuously all day.
In pulse ox glance, there is pulse ox and heart rate values
I can find two different places of pulse ox measurements in garmin connect app.
In one of those places, there is pulse ox axis on a left hand side and altitude axis on the right hand side. It is mentioned below a graph (Nadmořská výška = altitude). But it shows average of -1m (one meter below the sea level!)
Why?
Other Garmin watch seems to be capable of this:
Is my Venu 3 barometer broken?
