Adding logo

[akubisch]

Hi @sglyon,
It's me again :-) Next thing I would need to get to work is adding a logo to a plot. After researching a bit, this is the approach I tried:

myStyle = let
    logoImg = attr(source = "https://upload.wikimedia.org/wikipedia/commons/thumb/6/69/Julia_prog_language.svg/200px-Julia_prog_language.svg.png",
                  sizex = 0.2,
                  sizey = 0.2,
                  x = 0.5,
                  y = 0.5,
                  sizing = "stretch",
                  layer = "above",
                  visible = "true"
                  )
    layout = Layout(images = logoImg)

    Style(layout=layout)
end

trace1 = scatter(;x=1:4, y=[10, 15, 13, 17], mode="lines")
plot([trace1], style = myStyle)

When I execute that I just do not see the logo anywhere... Am I missing something obvious?
I also tried base64-encoding a local png file to create a png URI (which would be my favourite solution), but getting online graphs to work would of course be the first necessary step.

For a layout, the images may need to be an array...

Have you tried putting it in [] ?

That was too easy ;-) The following code works:

myStyle = let
    logoImg = attr(source = "https://upload.wikimedia.org/wikipedia/commons/thumb/6/69/Julia_prog_language.svg/200px-Julia_prog_language.svg.png",
                  sizex = 0.2,
                  sizey = 0.2,
                  x = 0.5,
                  y = 0.5,
                  sizing = "stretch",
                  layer = "above",
                  visible = "true"
                  )
    layout = Layout(images = [logoImg])
    Style(layout=layout)
end

trace1 = scatter(;x=1:4, y=[10, 15, 13, 17], mode="lines")
plot([trace1], style = myStyle)
