[英]Setting tooltip font in ggiraph 0.7 (R)
This may well be a CSS query rather than a {ggiraph} question, or may be to do with my R or Cairo installation, but here goes:这很可能是一个 CSS 查询而不是 {ggiraph} 问题,或者可能与我的 R 或 Cairo 安装有关,但这里是:
I'm building a ggiraph interactive plot, but the settings that I apply for tooltip options aren't applied to the printed plot.我正在构建一个 ggiraph 交互式 plot,但我为工具提示选项应用的设置并未应用于打印的 plot。
This is a reprex:这是一个代表:
library(tidyverse)
library(ggiraph)
test_df <- tibble::tribble(
~Index, ~This, ~That, ~Something.Else,
1L, 20L, 57L, "A",
2L, 22L, 58L, "B",
3L, 24L, 65L, "B",
4L, 26L, 68L, "A",
5L, 28L, 89L, "B",
6L, 30L, 93L, "B",
7L, 32L, 97L, "B",
8L, 34L, 101L, "A",
9L, 36L, 105L, "B",
10L, 38L, 109L, "B",
11L, 40L, 72L, "A",
12L, 42L, 76L, "B",
13L, 44L, 80L, "B",
14L, 46L, 84L, "A"
)
plot <- ggplot(test_df, aes(x = This, y= That, colour = Something.Else))+
geom_point_interactive(alpha = 0.8, aes(tooltip = That, data_id= Index))
tooltip_css <- "background-colour:transparent;font-family: Arial, Helvetica, sans-serif;"
ploti <- girafe(ggobj = plot, fonts = list(sans = "Helvetica"),
options = c(opts_sizing(width = 0.7)), opts_tooltip(css = tooltip_css))
print(ploti)

But the issue I have is that despite setting font-family to a sans-serif font, the tooltips are using a different font, plus the background-colour setting is ignored.但我遇到的问题是,尽管将 font-family 设置为 sans-serif 字体,但工具提示使用的是不同的字体,而且背景颜色设置被忽略。 What am I doing wrong?
我究竟做错了什么?

You need to put opts_tooltip
in the list for options
(see https://davidgohel.github.io/ggiraph/articles/offcran/customizing.html#tooltip-style ):您需要将
opts_tooltip
放在options
列表中(参见https://davidgohel.github.io/ggiraph/articles/offcran/customizing.html#tooltip-style ):
ploti <- girafe(ggobj = plot, fonts = list(sans = "Helvetica"),
options = list(
opts_sizing(width = 0.7),
opts_tooltip(css = tooltip_css)
)
)
