Add multiple lines to a plot_ly graph with add_trace

Question

I found an example to add lines to a plot_ly plot by using the add_trace command. How can I add a list of lines to plot without using add_trace

Answer 1

I believe with the release of plotly 4.0 calling any of the add_* family of functions forces evaluation so there is no need to call evaluate = T anymore

So, something like this should work fine:

devtools::install_github("ropensci/plotly")
library(plotly)

p <- plot_ly()

for(i in 1:5){
  p <- add_trace(p, x = 1:10, y = rnorm(10), mode = "lines")
}

p
