Hi, I can’t see the RRa1 chart. Can anyone help?
Do you have the RR and A1 streams in you activity fit file?
Show a screenshot from the activity page with the streams plotted.
Could you take a sample screenshot? I don’t fully understand 
These are my own personal charts but there are standard charts available which should show the data from the fit file. You need respiration and a1 in the fit file to get the RR/A1 chart.
I understand. I need DFA a1 data. I have a Garmin 530. Am I able to get this data?
Yes, Garmin 530 has support for IQ fields.
Install the IQ field named AlphaHRV found here:
Search this forum for installation configuration tips.
Thank you. I’ve already installed it. Teamt to close.
