【问题描述】:
我想更改我的 y 轴描述的文本大小并将我的 plottitle 居中。
主题函数中编码的所有内容都没有应用于我的图表。
问题出在哪里?
finalchart = ggplot(euall,
aes(day, cumulative_cases_of_14_days_per_100000 ,
group = countriesAndTerritories)) +
geom_bar(stat = "identity" ,
col = "white" ,
fill = "darkred") +
facet_wrap("countriesAndTerritories") +
geom_line(aes(y = rollmean(cumulative_cases_of_14_days_per_100000, 1,
na.pad = TRUE),
col = "pink"),
show.legend = FALSE) +
labs(title = "COVID infections in the European Union in September 2020" ,
x = "\nSeptember" ,
y = "Infections per 100'000\n" ,
caption = "source: https://opendata.ecdc.europa.eu/covid19/casedistribution/csv") +
theme(axis.text.y = element_text(size = 5) ,
axis.title.y = element_text(size = 10) ,
plot.title = element_text(hjust = 0.5)) +
theme_minimal()
finalchart
