Stacked ggplot & error bar

[ame_elm]

Hello,
I have a problem in R with my stacked ggplot. I add error bars (see the code above) but it seems that certain error bars are not properly positioned, i can't find an issue with that.

p <- ggplot(homme_N, aes(x=phoneme, y=score, fill=flow)) + geom_bar(stat = "identity", width = 0.3)+ scale_y_continuous(name = "Débit d'air (l/s)")+ scale_fill_discrete(name = "Débit d'air") + geom_errorbar(aes(ymin = score-sd, ymax = score+sd, group = flow), width=0.2)
p + theme(axis.text.x = element_blank())

p + facet_grid(col=vars(masque))

and the data frame

Hi @ame_elm, Welcome!

Try to put a better format like this:
Reproducible example

For the plot see this:

stacked bargraph with error bars

May I suggest that a stacked barchart ,especially with error bars, is a horrible way to plot the data?

Try something like this:

p <- ggplot(homme_N, aes(x=phoneme, y=score, colour =flow)) + 
   geom_point() + 
   scale_y_continuous(name = "Débit d'air (l/s)")+ 
    scale_fill_discrete(name = "Débit d'air") +
    geom_errorbar(aes(ymin = score-sd, 
    ymax = score + sd, group = flow), width=0.2)
