How to make the scale continuous in this facet plot?

Hi I am a still learning and trying to create a facet plot. I have try googling it but I can't find the right solution for it.

This is the code I used for the plot

met_ven %>%
  pivot_longer(c(14, 15, 19, 21, 22, 23, 24, 25, 27, 32, 33, 34),names_to="metabolites",values_to="Concentration") %>%
  ggplot(aes(x=factor(Day),y=Concentration)) + 
  geom_boxplot() + 
  facet_wrap(~metabolites, scales = "free", ncol = 3) +
  labs(title = "Venison")

The plot is showing a concentration of metabolites (y) at certain time point(x) variable are 0, 0.25, 0.79 1.25, 1.75 and 2.25.

From this code the plot giving me

Plot

From my understanding, using factor(Day) would put the Day in discrete but I dont want that. I want to do a box plot on a continuous scale.. but if I remove that ti x=Day

ggplot(aes(x=(Day),y=Concentration))

I get this

enter image description here

I want the plot to be like 1 on a continuous scale

If you want boxplots on a continuous scale, you'd have to set the group aesthetic appropriately. Example without group:

library(ggplot2)

df <- data.frame(
  x = sample(1:5, 30, replace = TRUE),
  y = runif(30)
)

ggplot(df, aes(x, y)) +
  geom_boxplot()
#> Warning: Continuous x aesthetic -- did you forget aes(group=...)?

Including the group:

ggplot(df, aes(x, y, group = x)) +
  geom_boxplot()
