问题
I am using the R programming language. 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? I was able to make an interactive time series 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)
)
However, I am having trouble adding custom titles and axis to this graph:
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
A similar error is produced when trying to change the x-axis of this graph :
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)
)

Can someone please tell me what I am doing wrong? Is it also possible to display the date over the hover text? Thanks
回答1:
I just figured out how to change the date to a more standard format:
a = data %>%
group_by(class) %>%
plot_ly(x = ~ (date_decision_made)) %>%
add_lines(y = ~ property_damages_in_dollars,
color = ~ factor(class)
)
Now, I have to figure out how to change the titles/axis, as well as make the date appear during the hover text
