Re-arranging the x-axis to show Julian Dates (e.g., 0-365) once for multi-year data-CodePudding

I have included the data and code needed to reproduce my current results. I have a single graph for different individuals (4), and they are data collected in different years. I currently have the x-axis as Julian Dates, so it shows the dates for each year.

I would like to get it to show the x-axis only from 0-365 once, instead of repeating it for multiple years. Is there a good way to accomplish this? I think essentially what I'm asking is if it is possible to condense these four lines into a single graph with the same x-axis and y-axis?

library(ggforce)
library(dplyr)
library(lubridate)

df <- read.csv("https://raw.githubusercontent.com/jhnhng/Data/main/NSD_Figure.csv")
df$t2  <- as.POSIXct(df$t2)

ggplot(ind_steps, aes(x = t2, y = NSD))  
  labs(x = "Julian Date", y = "Net Squared Displacement")  
  geom_line()   theme_bw()  
  theme(axis.text.x = element_text(angle = 90))  
  scale_x_datetime(date_breaks = '10 days', date_labels = '%j')  
  facet_wrap(~class, ncol = 1 , nrow = 4)

CodePudding user response：

df$t3 <- as.numeric(format(df$t2, "%j"))

then

ggplot(df, aes(x = t3, y = NSD))  
  ...
  scale_x_continuous(breaks = scales::breaks_width(10))  
  ...
