PlotPane

[tbreloff]

Hi @MikeInnes. I just started using Atom yesterday, and I was attempting to get Plots working with the PlotPane. I made an attempt at it, calling this method from Plots.__init__:

function setup_atom()
    @require Atom begin
        @eval begin
            import Atom

            Atom.displaysize(::AbstractPlot) = (535, 379)
            Atom.displaytitle(::AbstractPlot) = "Plots.jl"

            Atom.@render Atom.PlotPane p::Plot begin
                x, y = Atom.@rpc Atom.plotsize()
                plot!(p, size=(x,y))  # changes the size of the Plots.Plot
                Atom.div(Dict(:style=>"background: white"), Atom.HTML(stringmime("text/html", p)))
            end
        end
    end
end

but I end up with this error:

Any thoughts to debug it? It seems like one of the Atom packages is messing with eval internals, but it's kinda incomprehensible to me.

Side note... comments in the code would be much appreciated!

FYI... this works for me:

using Atom, Plots
p = plot(rand(10))
Media.render(Atom.PlotPane(), Atom.div(Atom.d(), Atom.HTML(stringmime(MIME("text/html"), p))))

[tbreloff]

I think I figured it out on my own!

function setup_atom()
    @require Atom begin
        import Atom, Media

        # connects the render function
        Media.media(Plot, Media.Plot)

        # Atom.displaysize(::AbstractPlot) = (535, 379)
        # Atom.displaytitle(plt::AbstractPlot) = "Plots.jl (backend: $(backend(plt)))"

        # this is like "display"... sends an html div with the plot to the PlotPane
        function Media.render(pane::Atom.PlotPane, plt::Plot)
            Media.render(pane, Atom.div(Atom.d(), Atom.HTML(stringmime(MIME("text/html"), plt))))
        end
    end
end

Any idea what the right methods are to set the size/title?

Great stuff! As a tip, you shouldn't need to have that @require method inside setup_atom(), since @require will make sure that things are run at module init time anyway (although the current Requires.jl approach is something we want to move away from).

Size and title only apply to BlinkDisplay windows, and won't have an affect on Atom's PlotPane (although we could perhaps reuse displaytitle here).

I think that should be true, but it actually stopped working for me. I had code in Plots that required DataFrames, and it wasn't running unless I called it from init. I guess I need to open an issue in Requires.

Ok it's not that important. Thanks.
