将评论中的所有内容放在一起,并按目标数量添加团队重新排序,代码如下
# add on: reorder teams by number of goals
scores$Team <- with(scores, reorder(Team, -Goals))
g <- ggplot(scores,
# keep all aesthetics in one place
aes(x = Team, y = Goals, color = Team, fill = Team, label = Goals)) +
# replacement of geom_bar(stat = "identity")
geom_col() +
# avoid overlap of text and bar to make text visible as bar and text have the same colour
geom_text(nudge_y = 1) +
# alternatively, print text inside of bar in discriminable colour
# geom_text(nudge_y = -1, color = "black") +
ggtitle("Goals per Team") +
xlab("Team") + ylab("Number of Goals") +
theme_bw() + theme(legend.position = "none") +
theme(plot.title = element_text(hjust = 0.5))
