First, your code is not reproducible. It errors out on my system.
waffle charts are a pie chart alternative and are designed to visualize counts of a small number of discrete categories (just like pie charts should be).
having said that, if you specify the proper # of colors you get what you want:
c("organophosphate catabolic process"=8, "transition metal ion transport"=7,
"multi-organism cellular process"=6,"growth"=6,
"cellular biogenic amine biosynthetic process"=6,
"protein maturation"=6,"indole-containing compound metabolic process"=6,
"reactive oxygen species metabolic process"=5,
"pyrimidine nucleobase metabolic process"=5,"carbohydrate phosphorylation"=4,
"negative regulation of hydrolase activity"=4,
"carbohydrate derivative transport"=4,"glutamate metabolic process"=4,
"indole-containing compound biosynthetic process"=3,"protein oligomerization"=3,
"regulation of cellular component movement"=3,"organophosphate ester transport"=3,
"(obsolete) ATP catabolic process"=3,"response to acid chemical"=2,
"hydrogen peroxide metabolic process"=2,"lipid oxidation"=2,
"glycosyl compound catabolic process"=2,"positive regulation of translation"=2,
"protein autophosphorylation"=2,"dicarboxylic acid transport"=2) -> processes
waffle(parts = processes,
title = "Biological Proccess",
colors = viridis::viridis_pal()(25))
With 25 colors, nobody is going to be able to keep track of the color-to-entity relationship. That's a big reason Color Brewer palettes top out at 12 (and only a few of them). This is visual jibberish:
waffle(parts = processes,
title = "Biological Proccess",
colors = {set.seed(1492); unname(randomcoloR::distinctColorPalette(25))})
as is:
waffle(parts = processes,
title = "Biological Proccess",
colors = c(brewer.pal(8, "Accent"), brewer.pal(8, "Dark2"), brewer.pal(9, "Set1")))
I'd consider re-thinking what you're trying to communicate.
thanks for the quick support!, you are right the colors are 8 but I need 25 (edited in first comment), although the pdf was made with 25 distinct colors (gradients are nice but a little useless to explain gene onthology terms), to communicate that i want to communicate, I need the colors be continuous, in this example, "transition metal ion transport" (second category), is "splited" by "organophosphate catabolic process" (first category) and "multi-organism cellular process" (third category). sure this is true looking from top to bottom, is there a way to transpose the waffle and get the colors begin top to right? or top to bottom and not bottom to top?. regards
Hi, When the are several categories, the little squares loss their color continuity, hindering the analyze step, the code is:
is there an solution ?, I attach the pdf regards
