添加不同的 colors 與 Plotly

Question

這段代碼生成累積柱 plot，如下面的 plot。 這是我的數據集的一個小例子。 該集合包含大約 52 周的每周數據。 您可以使用以下代碼查看數據：

# CODE
     #Data
library(tidyverse)
library(plotly)
      ARTIFICIALDATA<-dput(structure(list(week = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,

        "data.frame")))
colnames(ARTIFICIALDATA) <- c('week', 'series1', 'series2')

colnames(ARTIFICIALDATA) <- c("week", "series1", "series2")

ARTIFICIALDATA %>%
  # Drop rows with NA 
  drop_na() %>% 
  # Convert to long format
  pivot_longer(-week, names_to = "series") %>%
  # Set the labels for the plot. If you want other lables simply adjust
  mutate(label = case_when(
      series == "series1" ~ "2019 Series_1",
      series == "series2" ~ "2020 Series_1")) %>%  
  # Compute sum by sereis
  group_by(label) %>%
  summarise(sum = sum(value, na.rm = TRUE)) %>% 
  ungroup() %>%
  # Plot
  plot_ly(x = ~label, y = ~sum) %>% 
  add_bars() %>%
  # Remove title for xaxis. But can you can label it as you like
  layout(xaxis = list(title = ""))

但我的意圖是讓條形圖 plot 具有兩個不同的 colors，第一個條形圖為藍色，例如示例中的顏色，第二個條形圖為橙色。 那么有人可以幫我解決 colors 的這個問題嗎？

Answer 1

將add_bars()替換為

add_bars(marker = list(color = c("blue", "orange")))
