Hi all,
I’m getting the following issue when attempting to use savefig() with the Plots.jl package and plotlyjs() backend (note, Julia v0.5.0, Plots.jl v0.10.3, PlotlyJS.jl v0.5.2, Blink v0.5.1, on Ubuntu 16.04) . Oddly enough, I am able to successfully save a plot to .png, but the REPL pauses during the save operation with the below text. If I hit enter, I get back to a new line in the REPL and the plot has saved. So from a user perspective, the only issue is that I can’t set something to run and save plots while I move away from the keyboard, since I’ll need to hit enter every time a new plot is saved. So, I open Julia at the REPL and run the following commands:
julia> using Plots
julia> plotlyjs()
Plots.PlotlyJSBackend()
julia> p = plot(randn(10));
julia> savefig(p, “/home/colin/Temp/myplot.png”)
The following text is displayed the first time I run savefig (as above):
WARNING: bytestring(s::AbstractString…) is deprecated, use string(s…) instead.
WARNING: the no-optransposefallback is deprecated, and no more specifictransposemethod for ArgumentError exists. Considerpermutedims(x, [2, 1])or writing a specifictranspose(x::ArgumentError)method if appropriate. in

Error handling websocket connection:
MethodError: no method matching *(::ArgumentError, ::Blink.#msg)
Closest candidates are:
*(::Any, ::Any, ::Any, ::Any…) at operators.jl:138
Any subsequent calls to savefig will pause, but with the (greatly reduced) following text:
julia> no method matching *(::ArgumentError, ::Blink.#msg)
Closest candidates are:
*(::Any, ::Any, ::Any, ::Any…) at operators.jl:138
and, as with the first call, I can just hit enter and then get returned to a new line in the console and the plot has successfully saved.
Does anyone have any ideas about how I can resolve this? Even information on whether this a problem specific to my installation, or something affecting multiple users would be helpful.
Thanks in advance.
Colin
