On the Garmin website the Vertical Oscillation chart is missing in the running dashboard.
This is being recorded by my Garmin 6X Pro and HRM-RUN as it appears on the Connect app no problem
There is a tick box for the Vertical Oscillation chart on the Customise charts section but the tick box actually refers to the Vertical Ratio chart. (the VR chart is no good to me as I am trying to examine Vertical Oscillation independent of stride length.
I have a very bad experience with Garmin Support who keep asking questions that hint I do not know how to use the watch or HRM belt. The fact the app shows the correct graph means that the data is recorded correctly. Also the fact the the Web dashboard shows vertical ratio which is a function of stride length and Vertical oscillation means that the graph is just plain missing.
