What are the units on the first graph that magically puts fascism far right?
http://www.politicalcompass.org/ is a far more rational graph. Economic freedom on one axis, personal on another. Your graph seems meaningless.
Fascism has lowered economic and personal freedom. It has more economic freedom than the communist countries had, but LESS than any modern country (it was in fact a command economy—it looked like a market at first glance, but only "allowed" companies did business, so it was in no way a free market).
So fascist countries rightly belong left of modern countries in terms of economic freedoms, and are also more authoritarian (limits on personal freedom).
In the Nolamn chart, Libertarians are still on the far right of the graph. That graph is also broken because there is zero reason why the lower right should be called "right wing" (used in discussion of "normal" parties) since the normal political right (say in the US) is not the least authoritarian. Decentralized government is mutually exclusive with authoritarianism. That is the primary danger of socialism.
It is not dangerous in and of itself, but central control over people's lives means you are a single despot away from ruining everyone's life. When power is decentralized, one person is very limited in what they can do.
