Plots.jl pyplot() backend works (see example here) but with some limitations and PyPlot.jl seems to work best (see github post here).
PyPlot example below:
using PyPlot
fig = plt.figure()
ax = fig.add_subplot(111, projection="polar")
ρ = LinRange(0., 7, 200)
θ = LinRange(0., 2π, 360)
funp(ρ,θ) = sin(2ρ) * cos(θ)
pc = pcolormesh(θ, ρ, funp.(ρ,θ'))
cbar = plt.colorbar(pc)
cbar.set_label("Intensity")
ax[:grid](true)
