zoom to a region of the plot after log transformation

[Dani Linares]

Hi,
that works:

library("ggplot2")
df<-data.frame(x=c(1,2,3),y=c(10,100,500))
p<-ggplot(data=df,aes(x=x,y=y))+geom_line()
#p<-p+scale_y_log10()
p<-p+coord_cartesian(ylim = c(20,30))
p

but this doesnt work:

library("ggplot2")
df<-data.frame(x=c(1,2,3),y=c(10,100,500))
p<-ggplot(data=df,aes(x=x,y=y))+geom_line()
#p<-p+scale_y_log10()
p<-p+coord_cartesian(ylim = c(20,30))
p

sorry, the second piece of code should not have #

definitely, today is not my 'copy and paste' day

dani,

Currently, you'll need to manually transform the coord_cartesian limits:

df<-data.frame(x=c(1,2,3),y=c(10,100,500))
p<-ggplot(data=df,aes(x=x,y=y))+geom_line()
p<-p+scale_y_log10()
p<-p+coord_cartesian(ylim = log10(c(20,30)))
p
