3D Subplot

library(plotly)

# custom grid style
axx <- list(
  gridcolor='rgb(255, 255, 255)',
  zerolinecolor='rgb(255, 255, 255)',
  showbackground=TRUE,
  backgroundcolor='rgb(230, 230,230)'
)

# individual plots
fig1 <- plot_ly(z = ~volcano, scene='scene1') 
fig1 <- fig1 %>% add_surface(showscale=FALSE)

fig2 <- plot_ly(z = ~volcano, scene='scene2') 
fig2 <- fig2 %>% add_surface(showscale=FALSE)

fig3 <- plot_ly(z = ~volcano, scene='scene3') 
fig3 <- fig3 %>% add_surface(showscale=FALSE)

fig4 <- plot_ly(z = ~volcano, scene='scene4') 
fig4 <- fig4 %>% add_surface(showscale=FALSE)

# subplot and define scene
fig <- subplot(fig1, fig2, fig3, fig4) 
fig <- fig %>% layout(title = "3D Subplots",
         scene = list(domain=list(x=c(0,0.5),y=c(0.5,1)),
                      xaxis=axx, yaxis=axx, zaxis=axx,
                      aspectmode='cube'),

What About Dash?

Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

Learn about how to install Dash for R at https://dashr.plot.ly/installation.

Everywhere in this page that you see fig, you can display the same figure in a Dash for R application by passing it to the figure argument of the Graph component from the built-in dashCoreComponents package like this:

library(plotly)

fig <- plot_ly() 
# fig <- fig %>% add_trace( ... )
# fig <- fig %>% layout( ... ) 

library(dash)
library(dashCoreComponents)
library(dashHtmlComponents)

app <- Dash$new()
app$layout(
    htmlDiv(
        list(
            dccGraph(figure=fig) 
        )
     )
)

app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
