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

You need to set evaluate = TRUE to force evalutation / avoid lazy evaluation

p <- plot_ly()
p
for(line in my_lines) {  p <- add_trace(p, y=line[['y']], x=line[['x']], 
                 marker=list(color=line[['color']]),
                 evaluate = TRUE)
}
p
