PlotlyJS doesn't show plots on Julia 0.5 RC3.

[bicycle1885]

Even the simplest plot doesn't show anything though this may be due to a bug of an upstream.

Thanks for reporting.

Things work for me when I use 0.5-rc3.

Will you please try to open the javascript console on a notebook like that and tell me what you see?

I'm a bit worried that we don't see this message, which indicates that plotly.js has been successfully loaded into the notebook.

I reinstalled Jupyter and PlotlyJS.jl and cleaned all cache and settings related to Jupyter, and then I started to see a different error on my machine. This may not be related to PlotlyJS.jl (the message looks like JuliaInterop/ZMQ.jl#73), but happens just after calling using PlotlyJS:

Thank you for reporting.

I think that here is actually that your new jupyter installation didn't come with ipywidgets. Will you install that python library, either through pip install ipywidgets or conda install ipywidgets -- based on how your python installation is set up?

One more thing, on Julia v0.5-rc3 I had to do Pkg.checkout("IJulia") to get things working in the notebook. I guess there are some inconsistencies between recent version of the Jupyter notebook and the latest release of the IJulia.jl package

[bicycle1885]

Thanks a lot! Checking out the master branch of IJulia.jl solved the problem. Sorry for making noise.

[sglyon]

No problem, happy it helped!
