如何将条形图添加到 R plotly 条形图？

Question

我正在创建一个绘图图表，其中包含根据变量类别编码的各个条形图。我在保持条形颜色分类的同时向条形添加黑色轮廓时遇到问题。

下面是我当前的代码。我需要添加什么才能在每个栏上包含黑色轮廓？谢谢。

library(plotly)
library(tidyverse) 

my_tibble <- tibble(mins = runif(10,10,30),
                     week = 1:10,
                     exercise = c("a", "b", "b", "b", "a", "a", "b", "b", "b", "a"))

example_hex <- c('#70AD47', '#404040', '#CAE1F1', '#24608B')

plot_ly(
  data = my_tibble,
  type = 'bar',
  x = ~week,
  y = ~mins,
  color = ~exercise,
  colors = example_hex)

Answer 1

marker参数就是你想要的。

library(plotly)
library(tidyverse) 

my_tibble <- tibble(mins = runif(10,10,30),
                    week = 1:10,
                    exercise = c("a", "b", "b", "b", "a", "a", "b", "b", "b", "a"))

example_hex <- c('#70AD47', '#404040', '#CAE1F1', '#24608B')

plot_ly(data = my_tibble) %>% 
  add_trace(
    type = 'bar',
    x = ~week,
    y = ~mins,
    color = ~exercise,
    marker = list(line = list(color = "black", width = 5)))
