When using the R plotly package version 4.5.6 I haven't been able to figure out how to get axis labels to appear when combining multiple plots using subplot. Here is an example where no x-axis labels appear.

require(plotly)
a <- data.frame(x1=1:3,   y=30:32)
b <- data.frame(x2=11:13, y=31:33)

u <- plot_ly(a)
u <- add_lines(u, x=~x1, y=~y)
v <- plot_ly(b)
v <- add_lines(v, x=~x2, y=~y)
subplot(u, v, shareY=TRUE)

To get x-axis labels to show up with subplot, you can set titleX = TRUE. The default is titleX = shareX, and in your example, shareX = FALSE (the default).

subplot(u, v, shareY = TRUE, titleX = TRUE)
