`stat_summary_hex()` brings values or bins out of order

[aricht]

Hi all,
plotting with stat_summary_hex() the resulting plot does not look as expected and seems to not represent the underlying data. The difference to a plot generated with stat_summary_2d() is striking, when I would expect them to look very similar.
I observed this problem in ggplot2_3.4.0 but not ggplot2_3.3.5.

The problem can be seen on the example data:

library(ggplot2)
d <- ggplot(diamonds, aes(carat, depth, z = price))

d + stat_summary_2d()

d + stat_summary_hex()

Thanks a lot in advance for looking into this!

Thanks for reporting, this is already fixed in the dev version (#5045).

library(ggplot2)

d <- ggplot(diamonds, aes(carat, depth, z = price))

d + stat_summary_2d()

d + stat_summary_hex()
