Check altitude graph when navigating

I've set this as a question, but if not implemented it can be an idea. The altitude graph that appears when creating a route with the planner is great; I mean the graph on the bottom of the screen below:

But when navigating, i.e. after navigation has started, how can I access that graph? I would like to know where I am and what kind of altitude profile I will encounter while hiking. A point "you're here" on the graph would be great for example.

Is something already possible? Because I wasn't able to find how.
