GR plots does not appear in notebook

[Roger-luo]

My script contains a command that uses GR to plot. But when I set execute=true for notebook, it does not appear in the notebook (appears like the script is executed). Will this be possible to fix?

using GR
# ## Training target
function gaussian_pdf(n, μ, σ)
    x = collect(1:1<<n)
    pl = @. 1 / sqrt(2pi * σ^2) * exp(-(x - μ)^2 / (2 * σ^2))
    pl / sum(pl)
end

const n = 6
const maxiter = 20
pg = gaussian_pdf(n, 2^5-0.5, 2^4)
fig = plot(0:1<<n-1, pg)

This is a GR issue. GR does not show the plot as part of a show call.

[Roger-luo]

Oh, I see. I'll open an issue in GR's repo then. Thank you.

I think you can use GR with Plots.jl though, since Plots does not display until show is called.

Works fine on all platforms (in Jupyter notebook, nteract and Atom).

Which version() are you using (0.32.3?). Please try:

Pkg.update()
ENV["GRDIR"]=""
Pkg.build("GR")

actually I even tried the master branch...

It works fine in the notebook, but it does not work when you let Literate.jl to execute after converting the script to notebooks.

See #27, I mean the notebook function's execute keyword does not seem to work...
