Range breaks in plotly R

Hi,

Recently Plotly introduced breaks on date axes ( plotly v 4.6.0 ). They are pretty handy to remove weekends and missing dates while plotting. So far the fix was to make the Date as type =Category. But this makes the range slider not working. Thats also why this rangebreak was brought up. I dont know if its available in R yet.

A small workable script is given below

library(readr)
library(plotly)

a <- read_csv("https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv")

plot_ly(a[450:500,], x = ~Date, y = ~AAPL.High, type='scatter', mode = 'markers') %>%
  layout(xaxis =  list(
    rangebreaks= list (
      values= c("2016-12-25", "2016-12-24","2016-12-26","2017-01-01"))
  ))

Screenshot of the output:

This doesnt hide the missing dates, but it doesnt give any error either. I was wondering what am I doing wrong here.

Thanks

Bắt đầu bằng cách chạy ví dụ plot_ly() được cung cấp với layout(xaxis = list(rangebreaks = ...)) trên plotly 4.9.2.1 và so sánh kết quả với hành vi rangebreak trên trục ngày của Plotly. Truy vết cách R-to-Plotly xử lý xaxis rangebreaks và xác định liệu kết quả mong đợi có phải là ẩn các ngày bị thiếu trong khi vẫn giữ một range slider hoạt động hay không.
