I tried to connect several points in 3D plot. But it produced errors. Can you help me to add lines to some points rather than all points? Many thanks.
y must be length 1 or 61321, not 3, 3”
plot_ly(dc, x=~x, y=~y, z=~z, mode=“markers”,
color = day,
marker = list(size =5,opacity=1)) %>%
add_trace(x =c(0,0,0) , y= c(1,1,0) , mode = “lines”)
