Issue generating figures with a for loop

[Balinus]

Hello,

I get a strange error when trying the following code (a MWE).

for n = 1:3
    # data = matread(string(repData, ifile))["Maximums"]
    data = rand(3000, 4)

    obs = data[:, 1]
    sim = data[:, 2]
    qq = data[:, 3]
    mix = data[:, 4]
    trace1 = box(;y=obs, name = "OBS")
    trace2 = box(;y=sim, name = "SIM")
    trace3 = box(;y=qq, name = "QQ")
    trace4 = box(;y=mix, name = "MIXED")
    databox = [trace1, trace2, trace3, trace4]

    layout = Layout(;title = "Maximums (10 000 réalisations)")
    sp = PlotlyJS.plot(databox, layout)
    # filefig = string(repFigures, ifile[1:end-4], ".eps")
    filefig = string(repFigures, n, ".eps")
    PlotlyJS.savefig(sp::ElectronPlot, filefig)

end

I'm able to generate the figure and save it outside of the loop but not when I'm doing the loop. The error comes from the line
PlotlyJS.savefig(sp::ElectronPlot, filefig)

I get the following error

Hmm, that's strange.

Can report the version numbers you have for PlotlyJS and Blink?

[ghuba]

Can you try this?

for n = 1:3
    # data = matread(string(repData, ifile))["Maximums"]
    data = rand(3000, 4)

    obs = data[:, 1]
    sim = data[:, 2]
    qq = data[:, 3]
    mix = data[:, 4]
    trace1 = box(;y=obs, name = "OBS")
    trace2 = box(;y=sim, name = "SIM")
    trace3 = box(;y=qq, name = "QQ")
    trace4 = box(;y=mix, name = "MIXED")
    databox = [trace1, trace2, trace3, trace4]

    layout = Layout(;title = "Maximums (10 000 réalisations)")
    sp = PlotlyJS.Plot(databox, layout)
    # filefig = string(repFigures, ifile[1:end-4], ".eps")
    filefig = string(repFigures, n, ".eps")
    PlotlyJS.savefig(ElectronPlot(sp), filefig)
end

with

    sp = PlotlyJS.Plot(databox, layout)
    PlotlyJS.savefig(ElectronPlot(sp), filefig)

This works for me inside Jupyter.

Thanks @ghuba, it works in the REPL now. But, not with Juno.

Hence, when trying in the REPL, it works. It's only when I connect to Juno through ssh (i.e. using Juno; Juno.connect(local_ip) that it does not work.

when I connect to Juno and launch the MWE, I got an additional warning before I get the mentioned error:

WARNING: Method definition get_window(Base.Dict{K, V} where V where K) in module PlotlyJS at /home/proy/.julia/v0.6/PlotlyJS/src/displays/electron.jl:51 overwritten at /home/proy/.julia/v0.6/PlotlyJS/src/displays/juno.jl:21.

Tried with both the latest tagged and master releases of PlotlyJS and Blink.

savefig backend has been re-written and is much more reliable. Please try it out!

For now, please use the master branch

] # enter pkg mode
(v1.0) pkg> checkout PlotlyJS

If you want save figures you can do

] # enter package mode
(v1.0) pkg> add https://github.com/sglyon/ORCA.jl.git#master
