Question

我使用ggplotly绘制图形。当光标移动到图形顶部时，我使用工具提示功能来表示条形图中的值。

Source_Data <-
data.frame(
key = c(1, 1, 1, 2, 2, 2, 3, 3, 3),
Product_Name = c(
  "Table",
  "Table",
  "Chair",
  "Table",
  "Bed",
  "Bed",
  "Sofa",
  "Chair",
  "Sofa"
 ),
 Product_desc = c("XX", "XXXX", "YY", "X", "Z", "ZZZ", "A", "Y", "A"),
 sd = c(0.1, 0.3, 0.4, 0.5, 0.6, 0.7, 0.7, 0.8, 0.5),
 Cost = c(1, 2, 3, 4, 2, 3, 4, 5, 6)

 )


ggplotly((
Source_Data %>%
ggplot(
  aes(
    Product_Name,
    Cost,
    ymin = Cost - sd,
    ymax = Cost + sd,
    fill = Product_desc,
    text = paste("Product Name:", Product_Name, "<br>", "Cost:", Cost)
  )
  ) +
  geom_col(position = position_dodge2(width = .9, preserve = "single")) +
  geom_errorbar(position = position_dodge2(
  width = .9,
  preserve = "single",
  padding = .5
  )) +
  geom_text(
  aes(y = Cost + sd, label = Cost),
  position = position_dodge2(width = .9),
  vjust = -1
  ) +
  facet_wrap( ~ key, scales = "free_x", strip.position = "bottom") +
  theme(strip.placement = "outside") +
  theme_bw()
  ),
  tooltip = "text"
  )

当我将光标移到条形上方时，我会得到文本值，这很好。但是，当我将其移动到错误栏的顶部时，我也将获得不同颜色的文本值。有没有办法我只能在条形图的顶部而不是在错误条形图上获取文本/标签值？

您必须在text中设置geom_col的美感：

  Source_Data %>%
    ggplot(
      aes(
        Product_Name,
        Cost,
        ymin = Cost - sd,
        ymax = Cost + sd,
        fill = Product_desc
      )
    ) +
    geom_col(aes(text = paste("Product Name:", Product_Name, "<br>", "Cost:", Cost)),
             position = position_dodge2(width = .9, preserve = "single")) +
    ......
