Adding % values to upset plot top annotation

[nfarnoud]

Hello,

Is there a way I can add the % of the universal_set in addition to the number to the default annotation barplot in UpSet?
copy-pasting one of the examples here:

Thanks a lot,
Noush

lt = list(a = sample(letters, 5),
          b = sample(letters, 10),
          c = sample(letters, 15))

m1 = make_comb_mat(lt, universal_set = letters[1:10])

UpSet(m1, top_annotation = upset_top_annotation(m1, add_numbers = TRUE)) ## changing this to N(%) format
