I am assuming the learning limit indicated on the tooltip is the value in which the "Learning Limit Exceeded" penalty starts. In that case, what does the green line represents? It's not the hard cap as you can go well beyond it. It would be great to have an explanation on that.
Now, my suggestion is that the end of the green line should be the point where the "Learning Limit Exceeded" penalty starts and the zone between that and the hard learning cap of the skill should be in a different color so the player can see the actual limit of the skill.
Also, the learning limit tooltip should probably list its components too.
