Dear Felipe, Provide a dummy sample if your dataset is big or confidential. The actual values are not that important to figure out what kind of plot you want. How did you code Week? Numeric? Try convert it into a factor with levels = c(27:52, 1:26). And then set the breaks to seq(1, 52, by = 2).
WFBox <- data.frame(Week = rep(1:52, 10), FL = rnorm(520)) WFBox$fWeek <- factor(WFBox$Week, levels = c(27:52, 1:26)) library(ggplot2) ggplot(WFBox, aes(fWeek, FL)) + geom_boxplot(outlier.colour="pink",outlier.size=3,outlier.shape=21,fill= "goldenrod",colour="blue") + scale_x_discrete(breaks=c(seq(1,51,2))) HTH, Thierry ------------------------------------------------------------------------ ---- ir.

I have dealt with this before and I can't remember how it got resolved. It is too much data to reproduce the example below(49.000 records) but all I am after is trying to get the x axis breaks. I want my x axis to go from 27 to 51 and 1 to 25 by 2. I am trying to concatenate the breaks but it sorts the seq() in ascending order. Is there a way to workaround it? see scale_x_continuous below: boxP <- ggplot(WFBox, aes(Week, FL,group=Week)) boxP + geom_boxplot(outlier.colour="pink",outlier.size=3,outlier.shape=21,fill= "goldenrod",colour="blue") + scale_x_discrete(breaks=c(seq(27,51,2),seq(1,25,2))) Felipe D.
