Article 19 has generally increased its spending on regional programs evenly, with some notable exceptions. Prior to 2014, the bulk of its spending was directed to programs in Africa, wih a peak in 2013 of nearly £1,000,000. In the past couple years, however, African spending has been reduced, while global programs have increased, possibly as a replacement (though not entirely, since global programs were the second most funded category in 2013)

a19 <- read_csv("~/Desktop/a19.csv") %>%
  filter(!(Category %in% c("Governance", "Fundraising", "Law and policy"))) %>%
  group_by(Year, Category) %>%
  summarise(Amount = sum(Amount))
Parsed with column specification:
cols(
  Year = col_integer(),
  Subcategory = col_character(),
  Category = col_character(),
  Amount = col_integer()

a19.plot.amount

Looking at the percent of money spent on regional programs highlights this shift even better. Africa had been receiving roughly 30% of all funding until 2014, when Asia became more prominent. By 2015, all regions get between 12 and 22 percent.

a19.percent <- a19 %>%
  group_by(Year) %>%
  mutate(total = sum(Amount),
         percent = Amount / total)

  guides(colour=guide_legend(title=NULL)) +
