Reorder the values at the y axis in ggplot

tidyverse
#1

How can I reorder the values rising at the y axis using ggplot2 as below?

What I have done so far:

install.packages("tidyverse")
library(tidyverse)
Deutscher_Maschinenbau
ggplot(Deutscher_Maschinenbau,
aes(x = Jahr))+
geom_point(aes(y = Import, color = "1"), size = 5)+
geom_point(aes(y = Export, color = "2"), size = 5)

I'm sure this is very simple, but I can't find any examples out there.

Many, many thanks for your help!

Use scale_y_reverse(), take a look at this example:

library(ggplot2)

sample_df <- data.frame(
    x = 1:10,
    y = 1:10
)

ggplot(sample_df, aes(x = x, y = y)) +
    geom_point() +
    scale_y_reverse()

It looks as though your y axis isn't numeric.

Notice the differences here:

library(tidyverse)

tibble(x = c("1", "33", "100"),
       y = c(1,2,3)) |> 
  ggplot(aes(y = y, x = x)) +
  geom_point()


tibble(x = c("1", "33", "100"),
       y = c(1,2,3)) |>
  mutate(x = as.numeric(x)) |> 
  ggplot(aes(y = y, x = x)) +
  geom_point()

Hi Andreas, unfortunately, I don´t get any further. Can I provide you with the excel file than you can take a look? Any contact to you? Thank you

As I said, if you need further help, please provide a proper reproducible example as explained here

This looks to me like Jack's solution is what you need. It might be as simple as this:

ggplot(Deutscher_Maschinenbau,
aes(x = Jahr))+
geom_point(aes(y = as.numeric(Import), color = "1"), size = 5)+
geom_point(aes(y = as.numeric(Export), color = "2"), size = 5)
