NULL plot.margin breakdown the shape of the gtable

Related to #5628

I would like to change this line:

ggplot2/R/plot-build.R

Line 289 in 4dedb82

plot_margin <- calc_element("plot.margin", theme)

 plot_margin <- calc_element("plot.margin", theme)  %||% margin()

here is the problem:

copy your code to the clipboard and run:

library(ggplot2)
default_margin <- ggplot(mtcars, aes(disp, mpg)) +
    geom_point()
no_margin <- ggplot(mtcars, aes(disp, mpg)) +
    geom_point() +
    theme(plot.margin = NULL)
length(ggplotGrob(default_margin)$widths)
#> [1] 13
length(ggplotGrob(no_margin)$widths)
#> [1] 11
length(ggplotGrob(default_margin)$heights)
#> [1] 16
length(ggplotGrob(no_margin)$heights)
#> [1] 14

This proposal makes sense to me. Is there any way I can entice you to prepare a PR for this?

Thank you! I’ll go ahead and prepare a PR to move it forward.
