Hi Livia,
 From the look of your example, I suspect you may want more labels for 
the 31 bars of your histogram. The following will give you many more 
labels that don't overlap:

library(plotrix)
hist (data1, seq(-0.01,0.3,0.01),freq = FALSE,
main="Figure1.",xlab="return",lab=c(1,1,12),xaxt="n")
staxlab(1,at=seq(-0.01,0.3,by=0.02),labels=seq(-0.01,0.3,by=0.02))
