I'm new to using Plotly in R.

I am trying to construct a 3d line graph.

I am trying to achieve a graph that looks like this:

The above is my objective and I can't seem to make it work.

When I impliment what I think the right code is, I get one continuous line (so the last value of the first series line above is connected to the first value of the second series, etc).

Here is my result (you are viewing from an angle that shows the problem of the "looping"):

My code is here:

fig <- plot_ly(df_cohort_master, y = ~ord_month, x = ~cohort, z = ~conversions, 
                  type = 'scatter3d', mode = 'lines',color=~conversions) %>%
                  layout(
                    scene= list(
                      xaxis = list(autorange = "reversed"),
                      yaxis = list(autorange = "reversed")))

suppressWarnings(print(fig))

And here is what my data looks like:

What am I doing wrong?

Thanks in advance.

Perhaps you could try using split to separate into multiple traces based on your cohort.

Here's an example with made up data based on your post.

library(plotly)

set.seed(123)

df_cohort_master <- data.frame(
  cohort = rep(1:4, times = 5),
  ord_month = rep(1:4, each = 5),
  conversions = sample(20, 20)
)

plot_ly(df_cohort_master,
        x = ~cohort, 
        y = ~ord_month, 
        z = ~conversions, 
        type = 'scatter3d', 
        mode = 'lines',
        split = ~cohort) %>%
  layout(
    title = "3D Scatter plot", 
    scene = list(
      camera = list(
        eye = list(x = 1, y = 2, z = 2)
      )
    )
  )
