Plotting error #24

Closed lbittarello closed 7 years ago

lbittarello commented 8 years ago

I am having trouble reproducing the first plot in the ijulia notebook for PyPlot. I ran:

using PyPlot
using Distributions
using KernelDensity

plot(kde(X))

I get the following error message:

PyError (:PyObject_Call) <class 'TypeError'>

I'm running Julia 0.4.3 and Python 3.4.3. The packages are up to date. Do you know what I'm doing wrong?

Plotting functionality has been moved to https://github.com/JuliaPlots/StatPlots.jl

Please reopen there if it is still an issue.
