如何悬停每个栏的总数

Question

在代码的帮助下，我可以获得总值，但在悬停时显示总值的向量，所以我需要显示每个柱的单独总计，请帮助我实现

问题是您将总计的整个向量传递给了文本 aes。相反，我建议将组总计添加到您的数据框中，然后可以轻松地将其映射到 text aes:

library(plotly)

df1 %>%
  group_by(year_range) %>%
  mutate(total_year_range = sum(total)) %>%
  ungroup() %>%
  ggplot(aes(x = as.character(year_range), y = total, text = total_year_range)) +
  geom_col(aes(fill = Sector)) +
  theme_classic() +
  theme(axis.line.y = element_blank(), axis.ticks = element_blank(), legend.position = "bottom") +
  labs(x = "", y = "No.of total companies", fill = "") +
  theme(axis.title.y = element_text(size = 8)) +
  scale_fill_manual(values = c("#1F7A3F", "#0AAA4D", "#70B821", "#9BDFAF")) +
  scale_y_continuous(
    labels = function(x) format(x, scientific = FALSE),
    expand = expansion(mult = c(0, .3))
    #,breaks = integer_breaks()
  )

ggplotly(tooltip = c("text")) %>%
  layout(legend = list(
    orientation = "h", x = 0.1, y = -0.2,
    font = list(family = "Arial", size = 10, color = "black")
    #,xaxis = x_labels,yaxis = y_labels
  )) %>%
  config(displaylogo = FALSE, modeBarButtonsToRemove = list(
    "sendDataToCloud", "autoScale2d", "resetScale2d", "toggleSpikelines", "hoverClosestCartesian",
    "hoverCompareCartesian", "zoom2d", "pan2d", "select2d", "lasso2d", "zoomIn2d", "zoomOut2d"
  ))
