[BUG] Legend position broken on plotly(js)

[thevolatilebit]

After a recent update, legend position on plotly/plotlyjs backend is somewhat broken.

Namely, the attribute legend_position seems to have no effect on the resulting plot, and the rendered legend position is unpredictable - usually it's in the outer upper right corner (not good for longer labels), sometimes it's in the inner right corner - in that case, the background is white, not transparent.

Possibly related to #574 (will find time to investigate the fix).

On gr, this is fine.

Any way I (with basic Julia experience) can help with this?

One step forward would be to Figure out how one changes the legend Position in PlotlyJS

[Arpit-Babbar]

Looking only at the Julia side of things, I couldn't change the legend box. When I do

julia> plot(LinRange(0,1,10), ones(10), label = "test")

The final show command seems to be this JSON.print command, and the legend location seems to be stored in layout object. The legend position is stored in layout[:legend_position][:x], layout[:legend_position][:y]. However, even if change them there, nothing happens. That is, even after something crazy like

function plotly_show_js(io::IO, plot::Plot)
    data = plotly_series(plot)
     layout[:legend_position][:x] = 1000
     layout[:legend_position][:x] = 1000
    JSON.print(io, Dict(:data => data, :layout => layout))
end

the legend position still stays the same

Any suggestions on where to look next?

Any suggestions on where to look next?

I think the plotly documentation is the place to look for more Information

[ChasingZenith]

I think we should rename legend_position by legend

When I savefig as json, I found that everything that should be in layout.legend are in layout.legend_position

Sorry for having been misleading here

@BeastyBlacksmith Great!
