Hi, I have this code: par(mfrow=c(3,1)) x1=rnorm(10,60,1) x2=rnorm(10,65,1) x3=rnorm(10,70,1) boxplot(x1,x2,x3,horizontal=TRUE,main="Example 1") x1=rnorm(10,60,4) x2=rnorm(10,65,4) x3=rnorm(10,70,4) boxplot(x1,x2,x3,horizontal=TRUE,main="Example 2") x1=rnorm(10,60,9) x2=rnorm(10,65,9) x3=rnorm(10,70,9) boxplot(x1,x2,x3,horizontal=TRUE,main="Example 3") par(mfrow=c(1,1)) How can I set the horizontal axis limits on all three images to be the same for sake of comparison?

Setting axis scale for a boxplot

How can I set the horizontal axis limits on all three images to be the same for sake of comparison?
Add ylim=c(dataMin, dataMax) to each call to boxplot(), where
you specify values for dataMin and dataMax so their range is
likely to cover all your data. ('ylim', not 'xlim' - the horizontal=TRUE
flips the meaning of 'x' and 'y'.)

Hi David, In addition to Bill's answer where you specify limits at the beginning, if you want to do it "on the fly" and you are not reusing x1, x2 and x3: x1a=rnorm(10,60,1) x2a=rnorm(10,65,1) x3a=rnorm(10,70,1) x1b=rnorm(10,60,4) x2b=rnorm(10,65,4) x3b=rnorm(10,70,4) x1c=rnorm(10,60,9) x2c=rnorm(10,65,9) x3c=rnorm(10,70,9) ylim<-range(c(x1a,x2a,x3a,x1b,x2b,x3b,x1c,x2c,x3c)) boxplot(x1a,x2a,x3a,ylim=ylim,horizontal=TRUE,main="Example 1") boxplot(x1b,x2b,x3b,ylim=ylim,horizontal=TRUE,main="Example 2") boxplot(x1c,x2c,x3c,ylim=ylim,horizontal=TRUE,main="Example 3") Jim

Thanks, these replies worked. D. -- View this message in context: http://r.789695.n4.nabble.com/Setting-axis-scale-for-a-boxplot-tp4680704p4680821.html Sent from the R help mailing list archive at Nabble.com.
