把標簽從 plot 下來

Question

在這樣的plot 怎么可能把流的標簽從plot 下來

並且 mabel 黑色選項更胖，現在將這些條的標簽放在它旁邊的黑色列的中間

library(ggalluvial)
library(ggplot2)
library(dplyr)

df <- data.frame(status = c("open", "close", "close", "open/close", "close"), 
                 stock = c("google", "amazon", "amazon", "yahoo", "amazon"), 
                 newspaper = c("times", "newyork", "london", "times", "times"))

# Count the number of occurrences for each alluvial
df <- df %>% dplyr::group_by(stock, newspaper, status) %>% 
  summarise(n = n()) 

# Define the factors
df$status <- factor(df$status, levels = c("open", "open/close", "close"))
df$stock <- factor(df$stock, levels = c("google", "amazon", "yahoo"))
df$newspaper <- factor(df$newspaper, levels = c("times", "newyork", "london"))

# Plot the alluvial as in https://cran.r-project.org/web/packages/ggalluvial/vignettes/ggalluvial.html#alluvia-wide-format
ggplot2::ggplot(df.2, aes(y = n, axis1 = stock, axis2 = newspaper)) +
  ggalluvial::geom_alluvium(aes(fill = status), width = 1/12) +
  ggalluvial::geom_stratum(width = 1/12, fill = "black", color = "grey") +
  ggplot2::geom_label(stat = "stratum", aes(label = after_stat(stratum))) +
  ggplot2::scale_x_discrete(limits = c("stock", "newspaper"), expand = c(.05, .05)) +
  ggplot2::scale_fill_brewer(type = "qual", palette = "Set1")

Answer 1

你想要什么的描述很模糊。 據我所知，您希望將圖例移至 plot 的底部，並使地層條變寬：

ggplot(df, aes(y = n, axis1 = stock, axis2 = newspaper)) +
  geom_alluvium(aes(fill = status)) +
  geom_stratum(width = 1/5, fill = "black", color = "grey") +
  geom_label(stat = "stratum", aes(label = after_stat(stratum))) +
  scale_x_discrete(limits = c("stock", "newspaper"), expand = c(.05, .05)) +
  scale_fill_brewer(type = "qual", palette = "Set1") +
  theme_void() +
  theme(legend.position = 'bottom')
