[英]ggvis density plot with tooltip?
I'm trying to add a tooltip
to my ggvis plot. 我正在尝试为我的ggvis图添加
tooltip
。 I basically want to add the density number when I hover the mouse over the density plot. 当我将鼠标悬停在密度图上时,我基本上想要添加密度值。 This is what I have right now:
这就是我现在所拥有的:
mtcars %>% ggvis(~wt, fill := "red") %>%
layer_densities() %>%
add_axis("x", title = "Weight") %>%
scale_numeric("x", domain = c(0, 5), nice = FALSE, clamp = TRUE) %>%
add_tooltip(function(df){density(df$wt)})
But when I hover, I get this error: 但是当我悬停时,我收到此错误:
Error in density.default(df$wt) : argument 'x' must be numeric
Thanks! 谢谢!
I only have a partial answer, but it might help you in the right direction. 我只有部分答案,但它可能会帮助你朝着正确的方向前进。
The following code will give you a tooltip: 以下代码将为您提供工具提示:
mtcars %>% ggvis(~wt, fill:="red") %>%
layer_densities() %>%
add_axis("x", title = "Weight") %>%
add_tooltip(function(data){data$resp_}, "hover")
However, the tooltip contains the same value (ie: the first value of the density curve) for each x-value. 但是,工具提示包含每个x值的相同值(即:密度曲线的第一个值)。
With dens <- mtcars %>% compute_density(~wt)
you will get a density dataframe. 使用
dens <- mtcars %>% compute_density(~wt)
您将获得密度数据帧。
Hopefully someone else want to improve on this answer to get a complete solution.. 希望其他人想要改进这个答案,以获得完整的解决方案..
