How to create carpet plots in R with Plotly.

Plotly Studio: Transform any dataset into an interactive data application in minutes with AI. Sign up for early access now.

Set the Coordinates

To set the x and y coordinates use x and y attributes. If x coorindate values are ommitted a cheater plot will be created.

library(plotly)

fig <- plot_ly(
    type = 'carpet',
    y = c(2, 3.5, 4, 3, 4.5, 5, 5.5, 6.5, 7.5, 8, 8.5, 10))

Add Parameter Values

To save parameter values use a and b attributes.

library(plotly)

fig <- plot_ly(
    type = 'carpet',
    a = c(4, 4, 4, 4.5, 4.5, 4.5, 5, 5, 5, 6, 6, 6),
    b = c(1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3),
    y = c(2, 3.5, 4, 3, 4.5, 5, 5.5, 6.5, 7.5, 8, 8.5, 10))

Add Carpet Axes

Use aaxis or baxis lists to make changes to the axes. For a more detailed list of attributes refer to R reference.

library(plotly)

fig <- plot_ly(
    type = 'carpet',
    a = c(4, 4, 4, 4.5, 4.5, 4.5, 5, 5, 5, 6, 6, 6),
    b = c(1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3),
    y = c(2, 3.5, 4, 3, 4.5, 5, 5.5, 6.5, 7.5, 8, 8.5, 10),
    aaxis = list(
      tickprefix = 'a = ',
      ticksuffix = 'm',
      smoothing = 1,
      minorgridcount = 9
      ),
    baxis = list(
      tickprefix = 'b = ',
      ticksuffix = 'Pa',
      smoothing = 1,
      minorgridcount = 9
      )
    )

Style Carpet Axes

library(plotly)

fig <- plot_ly(
  type = 'carpet',
  a = c(4, 4, 4, 4.5, 4.5, 4.5, 5, 5, 5, 6, 6, 6),
  b = c(1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3),
  y = c(2, 3.5, 4, 3, 4.5, 5, 5.5, 6.5, 7.5, 8, 8.5, 10),
  aaxis = list(
    tickprefix = 'a = ',
    ticksuffix = 'm',
    smoothing = 1,
    minorgridcount = 9,
    minorgridwidth = 0.6,
    minorgridcolor = 'white',
    gridcolor = 'white',
    color = 'white'
  ),
  baxis = list(
    tickprefix = 'b = ',
    ticksuffix = 'Pa',
    smoothing = 1,
    minorgridcount = 9,
    minorgridwidth = 0.6,
    gridcolor = 'white',
    minorgridcolor = 'white',
    color = 'white'
  )
) 
fig <- fig %>% layout(
    plot_bgcolor = 'black', paper_bgcolor = 'black',
    xaxis = list(showgrid = F, showticklabels = F),
    yaxis = list(showgrid = F, showticklabels = F)
  )

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)
