使用 plotly 为多列制作折线图

Question

我有一个包含 4 列的数据框。日期、渠道、公司 A 测量值 (stat105) 和公司 B 测量值 (stat201)。

df <- data.frame(stringsAsFactors=FALSE,
     station = c("K P1", "K P1", "K P1", "K P1", "K P1", "K P1", "K P1",
                 "P1 +", "P1 +", "P1 +", "P1 +", "P1 +", "P1 +", "P1 +",
                 "K P2", "K P2", "K P2", "K P2", "K P2", "K P2", "K P2", "mP3", "mP3",
                 "mP3", "mP3", "mP3", "mP3", "mP3", "P13", "P13", "P13", "P13",
                 "P13", "P13", "P13"),
        date = c("2018-10-01", "2018-10-02", "2018-10-03", "2018-10-04",
                 "2018-10-05", "2018-10-06", "2018-10-07", "2018-10-01",
                 "2018-10-02", "2018-10-03", "2018-10-04", "2018-10-05", "2018-10-06",
                 "2018-10-07", "2018-10-01", "2018-10-02", "2018-10-03",
                 "2018-10-04", "2018-10-05", "2018-10-06", "2018-10-07", "2018-10-01",
                 "2018-10-02", "2018-10-03", "2018-10-04", "2018-10-05",
                 "2018-10-06", "2018-10-07", "2018-10-01", "2018-10-02", "2018-10-03",
                 "2018-10-04", "2018-10-05", "2018-10-06", "2018-10-07"),
     stat105 = c(0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 270L, 251L, 317L, 342L,
                 378L, 0L, 0L, 291L, 460L, 515L, 299L, 462L, 0L, 0L, 0L, 42L,
                 119L, 107L, 21L, 0L, 0L, 0L, 63L, 40L, 0L, 63L),
     stat201 = c(1221L, 1231L, 1176L, 1098L, 1092L, 952L, 826L, 310L, 310L,
                 289L, 268L, 252L, 312L, 316L, 245L, 254L, 261L, 246L, 227L,
                 143L, 181L, 114L, 104L, 134L, 158L, 183L, 153L, 152L, 108L, 126L,
                 113L, 127L, 137L, 64L, 87L)
)

我想 visualize/compare 公司 A 和公司 B 在折线图上每天每个渠道的测量。我使用 tidyr::spread 使我的数据整洁，但我的代码片段仅适用于一个变量 (stat105)。我怎样才能 compare/visualize 在折线图上同时显示 stat105 和 stat201

library(tidyverse)
library(plotly)

# create tibble
df <- as.tibble(df) %>%
  mutate(date = parse_date(date))

# tidy data  
df_2 <- df %>% 
  select(-stat201) %>% 
  spread(station,stat105) %>% 
  janitor::clean_names()


#create plot with plotly
p <- plot_ly(df_2, x = ~date, y = ~k_p1, name = 'k_p1', type = 'scatter', mode = 'lines',
             line = list(color = 'rgb(205, 12, 24)', width = 4)) %>%
  add_trace(y = ~k_p2, name = 'k_p2', line = list(color = 'rgb(22, 96, 167)', width = 4)) %>%
  add_trace(y = ~m_p3, name = 'm_p3', line = list(color = 'rgb(205, 12, 24)', width = 4, dash = 'dash')) %>%
  add_trace(y = ~p1, name = 'p1', line = list(color = 'rgb(22, 96, 167)', width = 4, dash = 'dash')) %>%
  add_trace(y = ~p13, name = 'p13', line = list(color = 'rgb(205, 12, 24)', width = 4, dash = 'dot')) %>%
  layout(title = "Change in something",
         xaxis = list(title = "Week"),
         yaxis = list (title = "something"))

Answer 1

这是一种使用 ggplot 然后使用 ggplotly 将其发送到 plotly 的方法：

df_3 <- df %>%
  gather(stat_type, value, stat105:stat201)  

my_blue <- "#1660a7"
my_red <- "#cd0c18"

a <- ggplot(df_3, aes(date, value, color = station, lty = station)) +
  geom_line() +
  facet_wrap(~stat_type, ncol = 1) +
  scale_color_manual(values = c(my_red, my_blue, my_red, my_blue, my_red)) +
  scale_linetype_manual(values = c("solid", "solid", "dashed", "dashed", "dotted")) +
  labs(title = "Change in something", x = "Week", y = "something")
ggplotly(a)
