使用 highcharter 自定义箱线图的颜色
Customize colors for boxplot with highcharter
我在 highcharter 上有箱线图，我想自定义
- 填充颜色
- 边框颜色
这是我的代码
df = data.frame(cbind(categ = rep(c('a','b','c','d')),value = rnorm(1000)))
hcboxplot(var = df$categ, x = as.numeric(df$value)) %>%
hc_chart(type = "column") %>%
hc_colors(c("#203d7d","#a0a0ed","#203d7e","#a0a0ad"))
hc_colors 仅当我将 var2 而不是 var 时才有效，但随后箱线图缩小了...
由于还没有highcharter答案，我至少给你一个基本的解决方案。
首先，您对数据框的定义有些缺陷，宁可：
dat <- data.frame(categ=c('a','b','c','d'), value=rnorm(1000))
现在，使用 boxplot 非常简单。 border 选项为您的边框着色。使用选项 col，您还可以为填充着色。
boxplot(value ~ categ, dat, border=c("#203d7d","#a0a0ed","#203d7e","#a0a0ad"), pars=list(outpch=16))

注意：请参阅 了解更多自定义设置。
API 样式 fillColor: https://api.highcharts.com/highcharts/series.boxplot.fillColor
对于"Border color"：https://api.highcharts.com/highcharts/series.boxplot.color
如何设置样式和定义点的纯 JavaScript 示例：https://jsfiddle.net/BlackLabel/6tud3fgx
和R代码：
library(highcharter)
df = data.frame(cbind(categ = rep(c('a','b','c','d', 'e')),value = rnorm(1000)))
hcboxplot(var = df$categ, x = as.numeric(df$value)) %>%
hc_chart(type = "column", events = list(
load = JS("function() {
var chart = this;
chart.series[0].points[2].update({
color: 'red'
})
chart.series[0].points[4].update({
x: 4,
low: 600,
q1: 700,
median: 800,
q3: 900,
high: 1000,
color: 'orange'
})
}")
)) %>%
hc_plotOptions(boxplot = list(
fillColor = '#F0F0E0',
lineWidth = 2,
medianColor = '#0C5DA5',
medianWidth = 3,
stemColor = '#A63400',
stemDashStyle = 'dot',
stemWidth = 1,
whiskerColor = '#3D9200',
whiskerLength = '20%',
whiskerWidth = 3,
color = 'black'
)) %>%
hc_colors(c("#203d7d","#a0a0ed","#203d7e","#a0a0ad"))
我做了几个函数来用高图和箱线图做一些事情。它会让您为每个箱线图着色并相应地填充它，然后根据 Highcharts API 注入新的图形参数，如果您愿意的话。

这可能可以调整为使用简单的数据框，但我认为它会立即为您提供您想要的东西，而无需做太多额外的工作。此外，也许可以查看 list_parse 或 list_parse2' fromhighcharter...it could probably help with building out theseries` 对象。我仍然需要查看它。
编辑：
我扩展了该示例，使其适用于常规 DF。根据一些后续问题，颜色是使用 make_highchart_boxplot_with_colored_factors 函数内的 viridis 调色板设置的。如果你想允许你自己的调色板和颜色，你可以公开这些参数并将它们作为参数包含在函数调用中。扩展示例借鉴了如何从 highcharter 库中添加离群值（尽管是以一种 hacky 的方式），然后从头开始构建其他所有内容。希望这有助于澄清我之前的回答。请注意，我可能还可以清理 if 条件以使其更简短一些，但出于说明目的，我将其保持冗长。
