How to reverse axis values when using plotly?

Question

Here is the program I used:

library(plotly)

mydata = read.csv("data_to_plot.txt")
df = as.data.frame(mydata)

p <- df %>%
  group_by(X) %>%
  plot_ly(x = ~Y, y = ~X, z = ~Z, type = "scatter3d", mode = "lines")
p  

and below is an excerpt of "mydata":

df[1:12,]
X Y Z
1 1 0.2818017 0.0005993884
2 1 0.2832173 0.0007896421
3 1 0.2846330 0.0010293849
4 1 0.2860487 0.0013282462
5 1 0.2874643 0.0016969544

I would like to have the X values reversed on the X-axis, but can't find how to modify my program. Details of the plotly syntax are quite obscure to me. Could someone afford some help? Many thanks.

You are probably looking for layout(xaxis = list(autorange = "reversed").
