Order of levels in ggplot2

[Jakub_Komarek]

Hi, I struggle to order the variables on the 'final' y-axis as I would like to? I want 'EPP'to be the first.

Thank you

ggplot(pos7,aes(x=factor(EPG,levels=c("EFFD","Greens/EFA","GUE/NGL","ALDE","ECR","S&D","EPP")),y=value,color=EPG,weight=seats))+
  geom_jitter(position=position_jitter(width=0.2,height=0),alpha=0.8)+
  geom_boxplot(alpha=0,show.legend=FALSE,lwd=1)+
  scale_color_manual(limits=c("EPP","S&D","ECR","ALDE","GUE/NGL","Greens/EFA","EFDD"),
                     values=c("#fcdd22","#fc1414","#106da8","#ec008c","#c6262c","#44911d","#00abbc"))+
  guides(color=guide_legend(""))+
  theme(legend.position="bottom", 
        axis.text.y=element_blank(),
        axis.ticks=element_blank())+
  labs(x="",y="",title="",subtitle=expression(paste("7"^"th", " European Parliament (Chapel Hill Expert Survey 2010)")))+
  facet_grid(variable~.)+
  coord_flip()

Hi Jakub!

To achieve that you need to change the order of EPG's levels, the plotting order follows the level order. In your case it seems like EPP is the last level of EPG, so try messing around with that.

You can find mode info on it here: Specific order for boxplot categories – the R Graph Gallery

Oh, and for future reference, it's advisable to provide a reprex along with your question. It makes it easier to help out

Cheers!
