Compose.jl text error

Specific Domains Visualization

I try to use compose.jl to represent a network. But I also want to write text next to it but I have an error using text.

I also tried to fix the network to make it not move at each iteration but it didn’t work.

Thanks for your help

using Plots
using GraphPlot
using LightGraphs
using Compose,Measures #Pour sauver l'image
using Printf #Pour sauver l'image
import Cairo #Pour sauver l'image Attention pas using
anim=Animation()
g = graphfamous("karate")
for i in 1:10
    p=gplot(g)
    output = compose(p,
        (context(), text(1, 1, "Julia", hcenter, vcenter), stroke("red"), fontsize(30pt)),
        (context(), rectangle(), fill("white")))
    j=length(anim.frames)+1
    tmpfilename=joinpath(anim.dir,@sprintf("%06d.png",j))
    draw(PNG(tmpfilename),output)
    push!(anim.frames, tmpfilename)
end
gif(anim, "anim_test.gif", fps = 5)

Hi there! I’d suggest including any using statements at the beginning of your code (since it will probably help people know which packages you’re using). People might then be able to copy/paste your code and run it to see what’s up.

Edit: that’s better…

    Compose.draw(PNG(tmpfilename),output)

So this ↑ works, but the few changes I made probably need investigating to find out what’s wrong. (Probably shouldn’t have changed more than one thing at a time… :slight_smile:)

Thanks ! Do you know how to make the network unmovable ?

I know ε about graphs, sorry. :smile:
