R：在 plotly 图（时间序列）上格式化轴和标题

Question

我正在使用 R 编程语言。 Using the following tutorial: https://plotly.com/r/time-series/ and this stackoverflow question: How to plot multiple series/lines in a time series using plotly in R? 我能够制作一个交互式时间序列 plot：

library(xts)
library(ggplot2)
library(dplyr)
library(plotly)
library(lubridate)

#time series 1
date_decision_made = seq(as.Date("2014/1/1"), as.Date("2016/1/1"),by="day")

property_damages_in_dollars <- rnorm(731,100,10)

final_data <- data.frame(date_decision_made, property_damages_in_dollars)

final_data %>%
  mutate(date_decision_made = as.Date(date_decision_made)) %>%
  add_count(week = format(date_decision_made, "%W-%y"))

final_data$class = "time_series_1"


#time series 2
date_decision_made = seq(as.Date("2014/1/1"), as.Date("2016/1/1"),by="day")

date_decision_made <- format(as.Date(date_decision_made), "%Y/%m/%d")

property_damages_in_dollars <- rnorm(731,10,10)

final_data_2 <- data.frame(date_decision_made, property_damages_in_dollars)

final_data_2 %>%
  mutate(date_decision_made = as.Date(date_decision_made)) %>%
  add_count(week = format(date_decision_made, "%W-%y"))

final_data_2$class = "time_series_2"

#combine
data = rbind(final_data, final_data_2)
data$class = as.factor(data$class)


a = data  %>% 
    
    group_by(class) %>% 
    plot_ly(x = ~ yday(date_decision_made)) %>% 
    add_lines(y = ~ property_damages_in_dollars, 
              color = ~ factor(class)
    ) 

但是，我无法在此图中添加自定义标题和轴：

with_titles = data  %>% 
    
    group_by(class) %>% 
    plot_ly(x = ~ yday(date_decision_made)) %>% layout(title = 'damages vs time', xaxis = 'time', yaxis = 'damage') %>%
    add_lines(y = ~ property_damages_in_dollars, 
              color = ~ factor(class)
    ) 

 with_titles

Error: $ operator is invalid for atomic vectors

尝试更改此图的 x 轴时会产生类似的错误：

with_titles_and_axis = data  %>% 

group_by(class) %>% 
plot_ly(x = ~ yday(date_decision_made)) %>% layout(title = 'damages vs time', xaxis = xaxis =list(type="date",
               tickformat='%d/%m/%Y',
               showticklabels='True',
                tick0= "2014-01-01",
                dtick= "M12"), yaxis = 'damage') %>%
add_lines(y = ~ property_damages_in_dollars, 
          color = ~ factor(class)
)

有人可以告诉我我做错了什么吗？ 是否也可以在 hover 文本上显示日期？ 谢谢

Answer 1

我刚刚想出了如何将日期更改为更标准的格式：

a = data  %>% 
    
    group_by(class) %>% 
    plot_ly(x = ~ (date_decision_made)) %>% 
    add_lines(y = ~ property_damages_in_dollars, 
              color = ~ factor(class)
    ) 

现在，我必须弄清楚如何更改标题/轴，以及使日期出现在 hover 文本中
