getGlobalXInfo truncates to nearest quarter

[HomoCodens]

When trying to get exact plots of windows that start/end at any month that is more annoying than useful.

This also leads to problems with the KOF Monatsblätter. Example:

x <- generate_random_ts(3, starts = 2018 + 6/12, lengths = 5)

tt <- init_tsplot_theme(
  fill_year_with_nas = FALSE,
  show_x_axis = FALSE,
  use_bar_gap_in_groups = FALSE
)

tsplot(x, left_as_bar = TRUE, group_bar_chart = TRUE, theme = tt)

usr_coords <- par("usr")
axis(
  1,
  seq(usr_coords[1], usr_coords[2], length.out = 6),
  hadj = -0.5,
  padj = -0.9
)

Here the bar groups should be evenly spaces across the whole plot to correspond with the manually drawn ticks. The example below makes it clear, that tsplot draws an additional empty month to fill the quarter:

x <- generate_random_ts(3, starts = 2018 + 6/12, lengths = 5)

tt2 <- init_tsplot_theme(
  fill_year_with_nas = FALSE,
  use_bar_gap_in_groups = FALSE
)

tsplot(x, left_as_bar = TRUE, group_bar_chart = TRUE, theme = tt2)

I guess this can be worked around with manual_ticks_x:

x <- generate_random_ts(3, starts = 2018 + 6/12, lengths = 5)

tt <- init_tsplot_theme(
  fill_year_with_nas = FALSE,
  use_bar_gap_in_groups = FALSE,
  show_x_axis = FALSE
)

bla <- tsp(x$ts1)

tsplot(x,
      left_as_bar = TRUE,
      group_bar_chart = TRUE,
      theme = tt,
      manual_ticks_x = seq(bla[1], bla[2] + 1/bla[3], by = 1/bla[3]))

usr_coords <- par("usr")
axis(
  1,
  seq(usr_coords[1], usr_coords[2], length.out = 6),
  c("Jul", "Aug", "Sept", "Okt", "Nof", ""),
  hadj = -0.5,
  padj = -0.9
)
