Customize Margins and Plot Size

library(plotly)
m <- list(
  l = 50,
  r = 50,
  b = 100,
  t = 100,
  pad = 4
)
fig <- plot_ly(x = seq(0, 8), y = seq(0, 8))
fig <- fig %>% layout(autosize = F, width = 500, height = 500, margin = m)

fig

Automatically Adjust Margins

library(plotly)
yaxis <- list(
  title = 'Y-axis Title',
  ticktext = list('long label','Very long label','3','label'),
  tickvals = list(1, 2, 3, 4),
  tickmode = "array",
  automargin = TRUE,
  titlefont = list(size=30)
)
fig <- plot_ly(x = c('Apples', 'Oranges', 'Watermelon', 'Pears'), y = c(3, 1, 2, 4), width = 500, height = 500, type = 'bar')
fig <- fig %>% layout(autosize = F, yaxis = yaxis)

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)
