Makie.jl: Segmentation fault for nested plots

[grahamas]

I may be doing this completely wrong and if so please tell me. I want to be able to plot an object, and have that plot actually be two plots inside a vbox. Eventually I want to be able to plot 2x2 of said objects, so that you really have a 4x2 figure (but sometimes the 2x2 will have objects that don't have nested plots, and then the resulting figure would also be 2x2 -- essentially the number and layout of plots will be determined by dispatch). If anyone can tell me how to do this, I would be extremely grateful.

I couldn't figure out how to do this by overriding plot! as a recipe, so I overrode plot. A seg fault ensued, and mercifully the MWE was the first thing I tried:

using AbstractPlotting

struct MyType
  a
  b
end

function AbstractPlotting.plot(mt::MyType, x)
  vbox(
    plot(x, mt.a),
    plot(x, mt.b)
  )
end

mt = MyType(1:10,2:11)

plot(mt, 0:9)

signal (11): Segmentation fault

Any advice much appreciated.

Probably better to use a custom function, the recipe interface doesn't support layouting

[SimonDanisch]

That looks like the wrong overload.
I'm guessing, that this is a hidden stack overflow - although this actually works for me on GLMakie#master & AbstractPlotting#master

[asinghvi17]

Can confirm this works on master.

[grahamas]

On further testing, it only segfaults when I'm using the Atom REPL. (tested both 1.2-rc2 and 1.3-alpha; using AbstractPlotting#master, GLMakie#master, and Makie#master)

[asinghvi17]

@pfitzseb we have another instance of this issue...are you on MacOS @grahamas?

[grahamas]

No, I'm on Arch Linux, using the Atom release binary (v1.38.2). (also on Ubuntu half the time; not sure if it errors there yet)

[pfitzseb]

What version of julia-client are you running, @grahamas? Updating Atom to 1.39.1 (which should be the latest version in the arch repos) might or might not help. I'll try this locally as soon as I can. Also, what Julia version are you on?

[grahamas]

@pfitzseb my julia-client is 0.8.10. I updated Atom to 1.39.1 as suggested but the problem persists. For Julia I've tried both 1.2-rc2 and 1.3-alpha. I could also try a stable version if you'd like.

[SimonDanisch]

The stack trace points to a julia compilation error...

[asinghvi17]

This is in Atom...same issue as earlier. Does it work with Julia 1.3 and the latest Juno ecosystem?

[SimonDanisch]

You should cross post this to julialang... Maybe, this is related: https://github.com/JuliaLang/julia/issues/30802
