将次轴作为折线图添加到 R 中的 DY 图

Question

我可以用下面的代码得到条形图。但是，我正在尝试将次轴作为折线图添加到半决赛列。我们可以添加这个吗？

mobility_aus_sum <- structure(list(Year = c(2020, 2020, 2020, 2020, 2020, 2020, 2020, 
                                            2020, 2020, 2020, 2020, 2021, 2021, 2021, 2021, 2021, 2021, 2021,

df3 <- ts(df2$Final, start = c(df2$Year[1], match(df2$mon_day[1], month.name)), 
          frequency = 12)

dygraph(df3) %>%
  dyRangeSelector() %>%
  dyBarChart()

你可以试试（需要下载barseries.js）

library(dplyr)
library(dygraphs)
library(tibble)
dyBarSeries <- function(dygraph, name, ...) {
  file <- "D:/barseries.js" #you need to link to the downloaded file
  plotter_ <- paste0(readLines(file, skipNul = T), collapse = "\n")
  
  dots <- list(...)
  do.call('dySeries', c(list(dygraph = dygraph, name = name, plotter = 
                               plotter_), dots))
  
}

mobility_aus_sum %>%
  mutate(mon_day = match(mon_day, month.name)) %>%
  rowwise %>%
  mutate(dates = paste0(c(Year, mon_day, 1), collapse = "-")) %>%
  mutate(dates = as.Date(dates, "%Y-%m-%d"))  %>%
  ungroup %>%
  select(-mon_day, -Year) %>% 
  column_to_rownames(var = 'dates') %>%
  dygraph(.) %>%
  dyAxis("y", label = "Final", valueRange = c(-1500, -200), independentTicks = TRUE) %>%
  dyAxis("y2", label = "Semi-Final ", valueRange = c(-1400, 0), independentTicks = TRUE) %>%
  dyBarSeries("Final") %>%
  dySeries("Semi-Final", axis=('y2')) %>%
  dyRangeSelector()
