I have seen the answer Pie charts in geom_scatterpie overlapping.
But I do not want to reset the overlapped pie chart coordinate manually.
Is there some function in ggplot2 or something else can avoid overlap in geom_scatterpie() function?
Any help will be highly appreciated!
Reproducible code is at here:
library(scatterpie)
library(tidyverse)
library(geosphere)
library(ggnewscale)
us <- map_data('state') %>% as_tibble()
n = length(unique(us$region))
# creat fake mapping data
temperature_data <- tibble(region = unique(us$region),
temp = rnorm(n = n))
coords <- us %>% select(long, lat, region) %>% distinct(region, .keep_all = T)
category_data <- tibble(region = unique(us$region),
cat_1 = sample(1:100, size = n),
cat_2 = sample(1:100, size = n),
cat_3 = sample(1:100, size = n)) %>% left_join(coords)
us <- left_join(us, temperature_data)
p +
geom_map(map = us, aes(map_id = region, fill = temp), color = 'grey') +
new_scale('fill') +
geom_scatterpie(data = category_data,
aes(long, lat),
cols = c("cat_1", "cat_2", "cat_3"),
alpha = 0.5)
