I changed the axis spacing, to fix the issue with narrow axis texts. What do you think? I could update the snapshot tests

[strengejacke]

hm... for some plots, the spacing between axis line and text increased, for others, it decreases when using theme_modern() with ggplot2 4. Not sure what to do, should we leave the code unchanged and accept closer distance when using that theme?

[IndrajeetPatil]

Yeah, I would leave it unchanged for now. Let's see if the users give any feedback about this. If they do, we can reassess.

There is one example failing involving geom_from_list? Could you please have a look?

[strengejacke]

Yes, will look into that failing test.
What about adding a new argument to set own values for the spacing?

[strengejacke]

This example fails, not sure why:

# code from example:
ggplot() + geom_from_list(list(geom = "density_2d_raster", data = iris, aes = list(x = "Sepal.Width", y = "Petal.Length")))

# equivalent ggplot code
ggplot() +
  geom_raster(
    data = iris,
    stat = "Density2d",
    aes(x = Sepal.Width, y = Petal.Length, fill = after_stat(density)),
    position = "identity"
  )

Source code changes are just 5-10 lines.

Most of the other changes are just SVG changes in snapshots. Unfortunately, this is going to be the case every time there is a major ggplot2 release.

This example fails, not sure why:

# code from example:
ggplot() + geom_from_list(list(geom = "density_2d_raster", data = iris, aes = list(x = "Sepal.Width", y = "Petal.Length")))

# equivalent ggplot code
ggplot() +
  geom_raster(
    data = iris,
    stat = "Density2d",
    aes(x = Sepal.Width, y = Petal.Length, fill = after_stat(density)),
    position = "identity"
  )

Perhaps contour = FALSE influenced the results?

library(ggplot2)
ggplot()+
  geom_raster(
    data = iris,
    aes(x = Sepal.Width, y = Petal.Length,fill = after_stat(density)),
    stat= "Density2d",
    position = "identity",
    contour = FALSE
  )
