Something like that yes, though I don't especially like the way that they break the axes down into "social" and "economic". As many libertarians are fond of criticizing of such a division, freedom is freedom, and limiting what people are allowed to do economically also limits what they're allowed to do socially, and vice versa. That chart's "libertarian left" isn't actually libertarian if it only favors social liberty but then also favors authoritarian intervention in economic matters.
The axes of my spectrum are not economic and social liberty vs authority; rather, they are libertarianism and egalitarianism. Those on the left think that everyone is, or should be treated as, equal; some of them favor using authority to enforce that equality, others believe it will emerge naturally if only proper liberty is ensured. Those on the right think that some people are naturally superior to others, or deserve more than others, with a zillion different ideas on the basis of that stratification (wealth, race, nationality, sex, religion, whatever); some of them favor using authority to enforce that stratification, others believe it will emerge naturally if only proper liberty is ensured. And both kinds of libertarian construct their notions of "proper liberty" such that if ensured it would (by their reckoning at least) result in the egalitarian or stratified result they expect/desire, or at least expect that result (and convince themselves it's desirable) because they reckon it would be the outcome of ensuring "proper liberty" as they conceive of it.
That other way of constructing the chart is actively ignoring the "upper left" corner of my spectrum, as happens all too often (and is part of what I'm complaining about here). The "upper left" of my chart is filled with libertarian socialists, an ideology almost completely unheard-of in America: the idea that the claim right to private property is what ruins the egalitarianism of libertarianism, and that what is known to Americans as anarcho-capitalism, minus the private property (but not plus a state to own that property; everything is simply unowned, and nobody has any claim to anything that would legitimize the use of force to deter others from making equal use of it), would yield a socialist form of libertarianism. (And in their terminology, "anarchism" simpliciter is a synonym with "libertarian socialism", in contrast to the authoritarian socialism of communism; and to them "anarcho-capitalism" is a contradiction in terms). The "libertarian left" of that other chart would be center left of my chart: those who favor a moderate exercise of authority only as necessary to ensure equality but no more. And Hitler would be, rather than bottom-center as on their chart, in the far lower right of my chart; not only was he heavily authoritarian, but also clearly believed in a stratification of society on the basis of race, religion, sex, orientation, etc. I'm not sure who they think was more right-authoritarian than Hitler.
Mind you I'm not an advocate of that upper-left corner of anarcho-socialism; I just think it's an important part of the political spectrum that's too often ignored as a possibility. We are so entrenched in the concept of private property that we only think about whether individuals should have the liberty to control some of it each themselves, or the state should have the authority to control it all, or what the balance between those should be; we forget that there is a whole school of thought that thinks we should abolish the concept entirely as antithetical to both liberty and equality. Again, not that I think that that's a good idea as such, but remembering that it's a possibility opens up room for thought. I place myself somewhere top-center on my own chart; between the anarcho-socialists and the anarcho-capitalists. I'm not able to place myself on that other chart because it's missing a whole corner of the spectrum (and has instead filled in an extraneous corner opposite it which I'm not rightly able to imagine the occupants of).
FWIW I also voted for Stein. I tend to vote either Green or Libertarian when given the option, trying to draw some attention both "upward" and "leftward", to counteract our country's slow sloping down and right. And though the Libertarians who actually run for office tend to run a bit right of my tastes, they're at least drawing attention upward toward liberty; and though the Greens may run a bit authoritarian to my tastes, they're really no worse and in many ways better in that respect than either modern Democrats or modern Republicans, and provide a nice solid leftward counterweight to our mainstream politics. I would love to see some kind of Libertarian-Green coalition, uniting on the common ground of social liberty against both the Democrats and Republicans, and then sorting out some kind of economic compromise after that at least is settled. But I don't expect to ever see that happen.
