Plots.jl: Polar coordinates

[tbreloff]

Example:

using Plots
pyplot()
plot(linspace(0,3π,100), rand(100), polar=true, m=:red, bg=:black)

Backends supported:

• [x] pyplot
• [ ] gadfly/immerse
• [x] plotly/plotlyjs
• [x] gr

Strangely, I just found out that the "radius axis" is scaled incorrectly on scatter plots. So this is broken:

scatter(linspace(0,3π,100), rand(100), polar=true)

but this is ok:

plot(linspace(0,3π,100), rand(100), polar=true, w=0, marker=:o)

I guess this is just one more reason to stop using matplotlib's scatter function, and just convert it to an equivalent plot call.

For future readers, polar=true became proj = :polar
