Hi Terence, thanks for your kind words about treemapify!
In ggplot2, the way a variable is expressed as a plot aesthetic is called a 'scale'. ggplot2 will automatically select a scale for each aesthetic, but you can manually override it with one of the scale_*()
family of functions. For example, you can manually specify the fill colours by adding scale_fill_manual()
to the plot:
library(ggplot2)
library(treemapify)
name <- c("France", "Germany", "Chad", "Mali")
population <- c(100, 200, 300, 400)
parent <- c("Europe","Europe","Africa","Africa")
df <- data.frame(name, population, parent)
ggplot(df, aes(area = population, label = name, subgroup=parent, fill=parent )) +
geom_treemap() +
geom_treemap_text(colour = "white", place = "centre", grow = TRUE) +
scale_fill_manual(values = c("purple", "orange"))

Hope this helps!
Perfect, thanks 😊
I love TreeMapify - it has made my life so much easier! Is there a way to specify the colours of the subgroups?
For example
The
fill=parent
seems to set the colours randomly. I thought I could change it tofill=c("red", "green" ...)
or use#f00
but neither of those worked.Is there a way to specify the fill colours?
Thanks!
