dates for config(locale = "nl") #2490

Description

@RianneLam96

When using config(locale = "nl") (Dutch) for data with dates, the month march is shown with the abbreviation "maa". In Dutch the default abbreviation of March is "mrt".

dates <- as.Date(c("2026-01-01", "2026-03-04", "2026-05-03", "2026-08-05", "2026-10-02"))
values <- c(10, 15, 7, 12, 9)
df <- data.frame(date = dates, value = values)

plot_ly(df, x = ~date, y = ~value, type = "scatter", mode = "lines+markers") %>% layout( xaxis = list(title = "Date"), yaxis = list(title = "Value") ) %>% config(locale = "nl")

When I look in plotly-locale-nl.js in shortMonths:["jan","feb","mrt","apr","mei","jun","jul","aug","sep","okt","nov","dec"], it is "mrt". So I cannot pinpoint where it is being altered to "maa". Is this something that can be fixed?

Thank you.

    It seems this was fixed in a later plotly.js version. R {ploty} is not using the latest plotly.js version.

    If you check your installation: ...\plotly\htmlwidgets\lib\plotlyjs\locales\nl.js

    or:

    You will find:
