[R] Issue with crammed Y axis

[Ana Marija]

Hi,

I have a data frame like this:

> dput(df)
structure(list(ID = 1:8, Type = c("gmx mdrun -ntmpi 8 -ntomp 1 -s
benchPEP.tpr -nsteps 10000 -resethway",
"gmx mdrun -ntmpi 8 -ntomp 1 -s benchPEP.tpr -nsteps 10000 -resethway",
"gmx mdrun -ntmpi 8 -s benchPEP.tpr -nsteps 4000 -resetstep 3000",
"gmx mdrun -ntmpi 8 -s benchPEP.tpr -nsteps 4000 -resetstep 3000",
"gmx mdrun -ntmpi 8 -s benchPEP.tpr -nsteps -1 -maxh 1.0 -resethway",
"gmx mdrun -ntmpi 8 -s benchPEP.tpr -nsteps -1 -maxh 1.0 -resethway",
"gmx mdrun -ntmpi 8 -ntomp 1 -s benchPEP.tpr -nsteps -1 -maxh 1.0
-resethway -noconfout",
"gmx mdrun -ntmpi 8 -ntomp 1 -s benchPEP.tpr -nsteps -1 -maxh 1.0
-resethway -noconfout"
), Annee = c("SYCL", "CUDA", "SYCL", "CUDA", "SYCL", "CUDA",

0.5, 0.6, 0.3, 0.7, 0.5, 0.7, 0.5)), class = "data.frame", row.names =
c(NA,
-8L))

I am plotting this data with:

library(reshape2)
library(ggplot2)

df <- read.csv("/Users/anamaria/Downloads/B5.csv", stringsAsFactors=FALSE,
header=TRUE)

df.long<-melt(df,id.vars=c("ID","Type","Annee"))

myplot =ggplot(df.long,aes(variable,value,fill=as.factor(Annee)))+
   geom_bar(position="dodge",stat="identity")+
   ylab("Simulation Progress (%)") +
   facet_wrap(~Type,nrow=3)

myplot + theme(panel.grid.major = element_blank(),
legend.title=element_blank(), panel.grid.minor = element_blank(),
panel.background = element_blank(), axis.title.x = element_blank(),
axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1),
axis.line = element_line(colour = "black"))

My issue is that Y axis is crammed. How it can be cleaned up and say
feature only say these values: 0, 10, 20,30, ...80.

I tried using: scale_y_continuous(breaks = breaks_width(10))+
But I got this error:
Error in breaks_width(10) : could not find function "breaks_width"

Also can anything be done about the subtitle of the top left plot, which is
not quite fitting in that gray box: "
gmx mdrun -ntmpi 8 -ntomp 1 -s benchPEP.tpr -nsteps 10000 -resethway"

Thanks
Ana
