You have to change levels of Make
by share
or volume
(provided data is already sorted):
dfc$Make <- factor(dfc$Make, levels = rev(as.character(dfc$Make)))
And play with theme
arguments:
ggplot(dfc[1:10, ], aes("", share, fill = Make)) +
geom_bar(width = 1, size = 1, color = "white", stat = "identity") +
coord_polar("y") +
geom_text(aes(label = paste0(round(share), "%")),
position = position_stack(vjust = 0.5)) +
labs(x = NULL, y = NULL, fill = NULL,
title = "market share") +
guides(fill = guide_legend(reverse = TRUE)) +
scale_fill_manual(values = c("#ffd700", "#bcbcbc", "#ffa500", "#254290")) +
theme_classic() +
theme(axis.line = element_blank(),
axis.text = element_blank(),
axis.ticks = element_blank(),
plot.title = element_text(hjust = 0.5, color = "#666666"))
