log-ratio profile: There should be two lines at hight zero between the two shadows

There should be two lines at high zero between the two shadows. This is particularly important when the two solvers perform very similarly, like in the above example.

These two lines correspond to the two solvers. Theoretically, they will be overlapping, but we can adjust a tiny bit the hights to make them distinguishable.

Thanks.
