It seems like the sizing of the bubble chart in the Training Log might be fixed? If so, we can’t see the scale. It definitely varies by activity.
For example, if the activity is “Run” and the distance is 5 mi, the bubble might be x1. If it’s 10 mi, then x2. If the activity is “Hike” and the distance is 20 mi, the bubble will be x1. However, at a distance of 30 mi the bubble still seems to be x1.
Could we have relative scaling based on our range of selected metric? Attaching a screenshot of what mine looks like on a 3 month long hike/kayak adventure.
