Idea to clean the graph - boluses and carbs treatment bubbles

[user-hash]

I want to recommend to de-clutter the graph specifically the bolus and carbs treatment value bubbles.
As I can see, there are already separate treatment bubbles in xDrip, which are assigned to positions 4 and 6 ( BG 4 and 6) on the graph, sometimes on both, sometimes only on one.

I do not understand the logic behind it, but the best solution would be to assign the Insulin treatment bubble to level 4 (BG 4.0 mmol), and carbs to level 6.
That way much more information can be present in zoomed-out view and xDrip already assigns the values to both of these levels.
The actual units (g, U) can be displayed on the right side of the screen to de-clutter even more, and carbs can have the same color as on the graph - my suggestion is to display carbs in orange.
The second picture is a mockup of my suggestion.
