Subplot fails to facet when Y-Axis contains missing values

Hi,

I have found that the subplot() function fails to facet when there are missing values in the Y-Axis.

For my use-case, showing breaks in a given time series is important and therefore I cannot simply remove the missing values.

Kind Regards,
Michael

library(reprex)
library(plotly)
library(dplyr)
library(tidyr)
economics %>%
  tidyr::gather(variable, value, -date) %>%
  transform(id = as.integer(factor(variable))) %>%
  mutate(value = replace(value, 1:10, NA)) %>%
  plot_ly(x = ~date, y = ~value, color = ~variable, colors = "Dark2",
          yaxis = ~paste0("y", id)) %>%
  add_lines() %>%
  subplot(nrows = 5, shareX = TRUE)

首先使用 plotly、dplyr、tidyr、economics 和 subplot(nrows = 5, shareX = TRUE) 运行 R reprex，以复现缺失 Y 值导致的失败。跟踪 subplot 的分面路径，并确定缺失值如何影响 y 轴分配；完成标准是示例被分面为五个子图，同时保留时间序列中的间断。
