Plot displaying - just getting PyObject

I'm using julia v0.6.0 in atom v1.22.1. I've installed pyplot after running ENV["PYTHON"]="". If I run:
`using PyPlot`
`plot(1:5,(1:5).^2)`
It returns a PyCall.PyObject and address, without displaying. Any ideas?

Reproduce the report in Julia v0.6.0 under Atom v1.22.1 after setting ENV["PYTHON"]="" and installing PyPlot. Start with `using PyPlot` and `plot(1:5,(1:5).^2)`; done means the plot displays instead of returning only a PyCall.PyObject address.
