geom_line_interactive中的固定工具提示

Question

我可能错过了一些非常非常明显的东西..。在示例2中，悬停文本显示'1'，指定的工具提示列的第一个值，并且不会更改。

我想有一个变化的悬停文本，如在示例1，而不是攻击f.e。颜色为y(如例2)

彩色

1. = y

testdf <- data.frame(
  "x" = c(1:10),
  "y" = c(1:10))

test <- testdf %>% 
  ggplot2::ggplot() + 
  ggiraph::geom_line_interactive(
    ggplot2::aes(x = x,
                 y = y,
                 color = y,
                 tooltip = y)
  )

ggiraph::girafe(ggobj = test,
                height_svg = 3.5,
                options = list(
                  opts_sizing(rescale = T),
                  # Gestaltung des tooltips
                  opts_tooltip(css= "font-family: Helvetica; padding:3pt; color:white; background-color:#15253F; border-radius:5px"),
                  # Zoom
                  opts_zoom(max = 5),
                  # Hover Optionen 
                  opts_hover(css = "stroke-width:2;"),
                  opts_hover_inv(css = "opacity:0.8"),
                  opts_toolbar(position = "topright", saveaspng = F) 
                  
                ))

无色

1. = y

testdf <- data.frame(
  "x" = c(1:10),
  "y" = c(1:10))

test <- testdf %>% 
  ggplot2::ggplot() + 
  ggiraph::geom_line_interactive(
    ggplot2::aes(x = x,
                 y = y,
                 tooltip = x)
  )

ggiraph::girafe(ggobj = test,
                height_svg = 3.5,
                options = list(
                  opts_sizing(rescale = T),
                  # Gestaltung des tooltips
                  opts_tooltip(css= "font-family: Helvetica; padding:3pt; color:white; background-color:#15253F; border-radius:5px"),
                  # Zoom
                  opts_zoom(max = 5),
                  # Hover Optionen 
                  opts_hover(css = "stroke-width:2;"),
                  opts_hover_inv(css = "opacity:0.8"),
                  opts_toolbar(position = "topright", saveaspng = F) 
                  
                ))

一种解决方案是添加一个geom_point_interactive来表示值。你可以用很小的一点(size = 0.05)来隐藏它们。

geom_point_interactive(aes(x = x,
             y = y,
             tooltip = x,
             data_id = x), size = 0.05)

如果您还想在整个行中获得一些信息，可以将其作为一个不同的变量添加到geom_line_interactive aes()中，即tooltip = "My line"

geom_line_interactive(aes(x = x,
             y = y,
             tooltip = "My line",
             data_id = x)) +
geom_point_interactive(aes(x = x,
             y = y,
             tooltip = x,
             data_id = x), size = 0.05)
