我有一个具有以下属性的数据集:
这里有一些示例代码:
dt <- tibble(
"location" = c("A", "B", "C", "D", "A", "B", "C", "A", "B", "C", "A", "B", "A", "A", "A"),
"months.since.start" = c(0,0,0,0,1,1,1,2,2,2,3,3,4,5,6),
"carer" = c("HCA", "nurse", "nurse", "dr", "HCA", "dr", "nurse", "HCA", "dr", "nurse", "dr", "HCA", "dr", "nurse", "HCA")
)
理想情况下,我想做的是两件事:
geom_text
)的比例重叠(在图B中)我知道它们在this post中解决的不同轴上起作用,但是我不需要显示图A的轴,它仅用于显示活动位置随时间的变化。
我怀疑可以通过将总数除以4(即活动位置的总数)来完成第一部分,然后将直方图放在比例计数之上,但是我不确定该怎么做。 / p>
答案 0 :(得分:0)
我已经设法回答了自己的问题-我认为我会提出而不是删除它,因为在其他任何地方都找不到(尽管我很欣赏这是相当简单的代码)。
这是情节:
这是上面剧情的代码:
dt %>%
ggplot(., size = 2, aes(months.since.start)) +
geom_histogram(binwidth = 1, # original chart with proportions
position = "fill",
aes(fill = carer)) +
geom_histogram(binwidth = 1, # the barchart with the total count
color = 'grey',
alpha = 0, # transparent boxes
aes(y=..count../4)) + # divided by the total number of locations (4 in this case), so that it becomes a fraction of 1 and therefore will fit within the y-axis
geom_text(stat = 'count',
aes(label=..count..),
position=position_fill(vjust=0.05), #the text, adjusted using position_fill, so that the position is fixed
color = 'white') +
theme_minimal()
