Dear Yu,

I'm facing the same problem. I tried to export to this case the solution given for barplots,

dotplot(egoBP,font.size=12) + scale_x_discrete(labels=function(egoBP) str_wrap(egoBP, width=10))

but it doesn't work for dotplot.

Have you provided a solution to this issue, because it severely affects the usability of dotplots for publication purposes when labels are too long...

Thanks in advance

Dear Yu,
Any insight or example on how to do this?

Hi,
I am sure I have find out the way to solve this.
please check this link: link.
Whether your native language is Chinese or not, I believe you can read it because the code and images are displayed in the text.
Have a nice day!

PSSUN solution only works for barplots and was already included in my first comment as "not working for dotplots".

use scale_y_ for dotplot.

Dear GuangchuangYu,
Thank you for the insight, now it works like charm.

Thanks, very helpful comments here. For completeness I'll add the code for dotplot() here:

plot1 = dotplot(my.enricher.obj) + scale_y_discrete(labels=function(x) str_wrap(x, width=40))

If you curate custom gene lists be aware that for text wrapping to be possible you need spaces in your term titles:

library("msigdbr")
custom.gene.lists = msigdbr(species = "Mus musculus", category = "H") %>% dplyr::select(gs_name, entrez_gene)
custom.gene.lists$gs_name = gsub("_", " ", custom.gene.lists$gs_name, fixed = TRUE)
my.enricher.obj = enricher(my.genes.entrez, TERM2GENE=custom.gene.lists)
