Ordering in r plotly barchart

Question

Why do I get the different order in plotly bar chart than I defined in x and y variables.

E.g.

library(plotly)

plot_ly(
  x = c(\"giraffes\", \"oran         


        

Answer 1

Plotly will order your axes by the order that is present in the data supplied. In case of character vectors alphabetically; in case of factors by the order of levels. To override this behaviour, you need to define categoryorder and categoryarray for the xaxis inside layout:

library(plotly)
xform <- list(categoryorder = "array",
              categoryarray = c("giraffes", 
                                "orangutans", 
                                "monkeys"))

plot_ly(
 x = c("giraffes", "orangutans", "monkeys"),
 y = c(20, 14, 23),
 name = "SF Zoo",
 type = "bar") %>% 
 layout(xaxis = xform)
