In R plotly subplot graph, how to show only one legend?

Question

I have a basic subplot with two graphs, both have a legend by default, but I want to see only one of them.

I tried this :

require(plotly)
p1 <- pl         


        

Answer 1

Maybe you can try a simple method. (plotly 4.9.2)

subplot(style(p1, showlegend = F), p2)

It will just show the legend of p2. Hope this works.
