Figure size not respected when axis lines not visible

[MonikaFu]

For some reason, Rmd/Latex decides to disregard plot dimensions when a void theme is used (or axis lines are made not visible).

Both this code:

{r alignment_table_equity, fig.height=4, fig.width=6, fig.align='center'}
empty_plot_no_data_message <- function() {
  p <- ggplot() +
    annotate(
      "text",
      label = "No data were found\nto create this plot",
      x = 0.5,
      y = 0.5,
      size = 6
    ) +
    coord_fixed(xlim = c(0, 1), ylim = c(0, 1)) +
    theme_classic() +
    theme(
      axis.line = element_line(colour = "#FFFFFF"),
      axis.ticks = element_blank(),
      axis.text = element_blank(),
      axis.title = element_blank()
    )
  p
}
empty_plot_no_data_message()

and this code:

{r alignment_table_equity, fig.height=4, fig.width=6, fig.align='center'}
empty_plot_no_data_message <- function() {
  p <- ggplot() +
    annotate(
      "text",
      label = "No data were found\nto create this plot",
      x = 0.5,
      y = 0.5,
      size = 6
    ) +
    coord_fixed(xlim = c(0, 1), ylim = c(0, 1)) +
    theme_void()
  p
}
empty_plot_no_data_message()

results in the plot dimensions being cut and the empty plot is squeezed in on one page with the other plot.

in contrast to when the axis are visible:

{r alignment_table_equity, fig.height=4, fig.width=6, fig.align='center'}
empty_plot_no_data_message <- function() {
  p <- ggplot() +
    annotate(
      "text",
      label = "No data were found\nto create this plot",
      x = 0.5,
      y = 0.5,
      size = 6
    ) +
    coord_fixed(xlim = c(0, 1), ylim = c(0, 1)) +
    theme_classic()
  p
}
empty_plot_no_data_message()

Code above results in this output (desired):

@AlexAxthelm maybe you can help with this.

[AlexAxthelm]

Huh. That's weird. I'll see if anything changes when I start putting stuff into LaTeX boxes.

As a hacky workaround, maybe we set axis & text color to white, so it's there, but invisible?

[MonikaFu]

@AlexAxthelm I tried your suggestion already, see the first chunk of code in the description. Doesn't work.

[AlexAxthelm]

Well, that's even weirder. I'll keep trying it from the LaTeX side.

does axis.line = element_line(colour = "#FFFFFE"), work?

[MonikaFu]

no, that's exactly what I tried :D
