我的数据（来自李克特量表问题）如下所示：

head(dat)
            Consideration Importance2           Importance  Percent Count
1         Aesthetic value           1 Not at all important 0.046875     3
2         Aesthetic value           2 Of little importance 0.109375     7
3         Aesthetic value           3 Moderately important 0.250000    16

dput(head(dat,6))
structure(list(Consideration = structure(c(2L, 2L, 2L, 2L, 2L, 
12L), .Label = c("", "Aesthetic value", "Affordability/cost-efficiency", 
"Climate change reduction", "Eco-sourcing", "Ecosystem services provision", 
"Erosion mitigation", "Habitat for native wildlife", "Habitat/species conservation", 
"Human use values", "Increasing biodiversity", "Planting native species", 
"Restoring ecosystem function", "Restoring to a historical state"
), class = "factor"), Importance2 = c(1L, 2L, 3L, 4L, 5L, 1L), 
    Importance = structure(c(4L, 5L, 3L, 2L, 6L, 4L), .Label = c("", 
    "Important", "Moderately important", "Not at all important", 
    "Of little importance", "Very Important"), class = "factor"), 
    Percent = c(0.046875, 0.109375, 0.25, 0.375, 0.234375, 0), 
    Count = c(3L, 7L, 16L, 24L, 15L, 0L), percentage = c(5L, 
    11L, 25L, 38L, 23L, 0L)), row.names = c(NA, 6L), class = "data.frame")

我使用堆积条形图绘制了结果。我想知道如何修改它，使它成为一个发散的堆积条形图，如下图所示，以 Importance2 级别 3（中等重要）为中心。 例子

我知道有一个名为 likert 的包可以用于此，但我认为我的数据格式不正确。

我现有情节的代码是：

ggplot(dat, aes(x = Consideration, y = Percent, fill = forcats::fct_rev(Importance2))) +
  geom_bar(position="fill", stat = "identity", color = "black", size = 0.2, width = 0.8) +
  aes(stringr::str_wrap(dat$Consideration, 34), dat$Percent) +
  coord_flip() +
  labs(y = "Percentage of respondents (%)") +
  scale_y_continuous(breaks=c(0, 0.25, 0.50, 0.75, 1), labels=c("0", "25", "50", "75", "100")) +
  theme(axis.title.y=element_blank(), panel.background = NULL, axis.text.y = element_text(size=8), legend.title = element_text(size=8), legend.text = element_text(size = 6)) +
  scale_fill_manual(name="Scale", breaks=c("1", "2", "3", "4", "5"), labels=c("Not at all important", "Of little importance", "Moderately important","Important", "Very important"), values=col3)

我尝试了几种解决方案，但我认为最简单的一种是将数据转换为likert()函数，这很简单：

library(tidyr)
# you need the data in the wide format
data_l <- spread(dat[,c(1,3,4)], key = Importance, value = Percent)
# now add colnames
row.names(data_l) <- data_l$Consideration
# remove the useless column
data_l <- data_l[,-1]

现在您可以使用：

library(HH)
likert(data_l , horizontal=TRUE,aspect=1.5,
       main="Here the plot",
       auto.key=list(space="right", columns=1,
                     reverse=TRUE, padding.text=2),
       sub="Here some words")

您可以调整ggplot以执行此操作，但在这种情况下，您不会以您想要的类的中心为中心，而是以它的“边缘”为中心。
