Yes

Explanation:

But you need a lot of them, at different pressures. From each cooling curve, you can identify the boiling/melting point from the plateau region, at that specific pressure.

A phase diagram needs information about a substance's physical state at a given temperature and pressure. It is the boundaries between the states that is important when constructing the phase diagram.
