It is not immediately clear whether Figure 2 is an averaged
experimental plot or a theoretical plot according to some model. If it
is experimental, it would be nice to also include a plot according to
the van der Waals equation (because you have some experimental plots
and a model formula with no way to compare the two directly).

More on Figure 2: it doesn't include regions where Z > 1, while Figure
1 does. Why the discrepancy?
