ggplot2::coord_fixed() margin problem

Hi,
  I posted this on the Google Group for ggplot2 but got no response.
https://groups.google.com/g/ggplot2/c/441srnt6RZU

So I hope someone can help me here instead?!

If I don't use the coord_fixed() then all the background is yellow as
expected.
But I need to coord_fixed() and then it adds a little white around my plot.
Is it possible to avoid the white and use coord_fixed() ?

Here is a "Minimal, Reproducible Example":

library(ggplot2)
g <-
  ggplot() +
  theme(
     plot.background = element_rect(fill = "yellow2"),
     panel.background = element_rect(fill = "yellow2"),
  )
g <- g + coord_fixed()
g

Hello,

I am not sure I understand the problem.
With coord_fixed() both axis have the same length and the plot is a 
square. When resizing the plot window the white areas can be on 
top/bottom if the window height is bigger than its width or to the 
left/right if it's the other way around.

Does this answer the question?

Hope this helps,

Rui Barradas

Yes.
Nope.
I really need the added space as the same color as the plot.background
(yellow2) in the example below.
However the code below generates a small white space. I was expected it to
be the
same as the plot.background color.

library(ggplot2)
g <-
   ggplot() +
   theme(
      plot.background = element_rect(fill = "yellow2"),
      panel.background = element_rect(fill = "yellow2"),
   )
g <- g + coord_fixed()
g

Set the background when you open the graphics device.  Assuming you've 
run the code above,

dev.new(bg = "yellow2")
g

You'll still see the outline of the square; I don't know ggplot2 well 
enough to know if that can be removed.

Hello,

Is it this?

plot.background = element_rect(colour = "yellow2", fill = "yellow2")

The small white space goes away.

Hope this helps,

That works with my suggestion:

g <-
   ggplot() +
   theme(
      plot.background = element_rect(fill = "yellow2", colour = "yellow2"),
      panel.background = element_rect(fill = "yellow2"),
   )
g <- g + coord_fixed()
dev.new(bg = "yellow2")
g  # For a pure yellow plot window
