Projection option for add_subplot

[adamnemecek]

Hello,
When I call fig.add_subplot with the projection option, I get an error.

Code:

using PyPlot
fig = plt.figure()
ax = fig[:add_subplot](111, projection="3d")

Error:

ERROR: PyError ($(Expr(:escape, :(ccall(#= /Users/adamnemecek/.julia/packages/PyCall/ttONZ/src/pyfncall.jl:44 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class 'ValueError'>

Actually this was a problem on my end. My bad.
