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", "orangutans", "monkeys"),
y = c(20, 14, 23),
name = "SF Zoo",
type = "bar"
)
I need bar chart where I see bars in the same order as x variable (categorical) is defined. Is there any trick for that?
Answer
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)
