Note: We are retiring documentation for R, MATLAB, Julia, and F# in November 2025. Learn more about this change here.

Default stair plot

library(plotly)
library(ggplot2)

d=data.frame(x=c(1,2,4,5,7,8,9), y=c(1,2,3,5,6,7,9))
p <- ggplot() +
      geom_step(data=d, mapping=aes(x=x, y=y)) +
      geom_step(data=d, mapping=aes(x=x, y=y), direction="vh", linetype=3) +
      geom_point(data=d, mapping=aes(x=x, y=y), color="red")

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)
