Warning when combining `coord_radial()` and absolute `theme(panel.widths)`

[jbengler]

Hi Teun,

is there a way to produce pie charts with absolute dimensions without triggering a warning?

library(ggplot2)

data.frame(cat = c("A", "B", "C"), value = c(25, 40, 60)) |>
  ggplot(aes(x = NA, y = value, fill = cat)) +
  geom_col(position = position_stack()) +
  coord_radial(theta = "y", expand = FALSE) +
  theme(panel.widths = unit(50, "mm"), panel.heights = unit(50, "mm"))

Warning message:
Aspect ratios are overruled by `panel.widths` and `panel.heights` theme elements. 

At the moment these warnings are spoiling my package tests 🙃

Not currently, but there is some room to explore finetuning when this warning appears.

Is there something I could do on my end?
