使用r-highcharter添加时间轴样式图形

Question

我在R中使用 highcharter 库创建了水印图。 我想将另一个变量（或使用任何现有变量调整值）添加到此图中作为时间轴（如图所示）。 此变量的值表也是时间序列数据帧，但值为“0”和“1” 其中“0”表示没有洪水，“1”表示洪水。 所以我想将（仅值“1”）显示为洪水持续时间作为时间线。

library(ggplot2)
library(dplyr)
library(highcharter)
Year_2005_rain <- subset(Seven, 
                         time >= as.Date('2005-04-01') & 
                         time <= as.Date('2005-10-31'))
Year_2005_flow<- subset(Seven_flow, 
                        time >= as.Date('2005-04-01') & 
                        time <= as.Date('2005-10-31'))
Year_2005_inflow<- subset(Seven_inflow, 
                          time >= as.Date('2005-04-01') & 
                          time <= as.Date('2005-10-31'))

merge1_05 <- merge(Year_2005_rain,
                   Year_2005_flow,
                   Year_2005_inflow, by="time")

names(Year_2005_rain) <- names(Year_2005_flow) <- names(Year_2005_inflow)
merge1_05 <- rbind(Year_2005_rain, Year_2005_flow,Year_2005_inflow)

colnames(merge1_05)[colnames(merge1_05)=="time"] <- "date"
colnames(merge1_05)[colnames(merge1_05)=="Discharge"] <- "value"

merge1_05$date = as.Date(merge1_05$date, format = "%Y/%m/%d")    
merge1_05$variable <- c(rep("rain", 214), rep("discharge", 214), rep("inflow", 214))

hc_14<- highchart() %>% 
  hc_yAxis_multiples(list(title = list(text = "rainfall depth (mm)"), reversed = TRUE), 
                     list(title = list(text = "flow (m3/s)"), opposite = TRUE)) %>% 
  hc_add_series(data = filter(merge1_05, variable == "rain") %>% 
                mutate(value = value) %>% .$value, type = "column") %>% 
  hc_add_series(data = filter(merge1_05, variable == "discharge") %>% .$value,   
                type = "spline", yAxis = 1) %>%
  hc_add_series(data = filter(merge1_05, variable == "inflow") %>% .$value,  
                type = "spline", yAxis = 1) %>%
  hc_xAxis(categories = merge1_05$date, title = list(text = "date"))

  hc_14
