R help - Nov 2023 - ggplot adjust two y-axis

Dear R-users

Is it possible to adjust two y-axis in a ggplot differently?
- First y axis (0-60)
- Second y axis (0-2500)


### Figure 1
ggplot(Fig1,aes(BFF,Wert,fill=Studien_Flaeche))+
  geom_bar(stat="identity",position='dodge')+
  scale_y_continuous(name="First Axis", sec.axis=sec_axis(trans=~.*50,
name="Second Axis"))+
  scale_fill_brewer(palette="Set1")

Thanks a lot
Sibylle

Hi Sibylle, 
For that kind of data with two different scales, I generally use two graphs
that I name gg1 and gg2 and join them using gridExtra::grid.arrange(gg1,
gg2). This way, the red part of your graph is easier to interpret. 
Have a nice day,
