1. 数据读取与处理

首先，从TSV文件中读取数据，并进行数据清洗和处理。

rm(list=ls())
pacman::p_load(tidyverse,ggalt,ggHoriPlot,hrbrthemes)

sports <- read_tsv("activity.tsv")

2. 数据清洗

sports <- sports %>%group_by(activity) %>% filter(max(p) > 3e-04, !grepl('n\\.e\\.c', activity)) %>% arrange(time) %>%mutate(p_peak = p / max(p), p_smooth = (lag(p_peak) + p_peak + lead(p_peak)) / 3,p_smooth = coalesce(p_smooth, p_peak)) %>% ungroup() %>%do({ rbind(.,filter(., time == 0) %>%mutate(time = 24*60))}) %>%mutate(time = ifelse(time < 3 * 60, time + 24 * 60, time)) %>%mutate(activity = reorder(activity, p_peak, FUN=which.max)) %>% arrange(activity) %>%mutate(activity.f = reorder(as.character(activity), desc(activity)))

sports <- mutate(sports, time2 = time/60)

3. 绘制初步图表

根据处理后的数据生成初步图表，展示不同体育活动在一天中的分布情况。

ggplot(sports, aes(time2, p_smooth)) +geom_horizon(bandwidth=0.1) +facet_grid(activity.f~.) +scale_x_continuous(expand=c(0,0), breaks=seq(from = 3, to = 27, by = 3), labels = function(x) {sprintf("%02d:00", as.integer(x %% 24))}) +viridis::scale_fill_viridis(name = "Activity relative to peak", discrete=TRUE,labels=scales::percent(seq(0, 1, 0.1)+0.1))

4. 美化图表

进一步美化图表，使其更具吸引力和可读性。

ggplot(sports, aes(time2, p_smooth)) +geom_horizon(bandwidth=0.1) +facet_grid(activity.f~.) +scale_x_continuous(expand=c(0,0), breaks=seq(from = 3, to = 27, by = 3), labels = function(x) {sprintf("%02d:00", as.integer(x %% 24))}) +viridis::scale_fill_viridis(name = "Activity relative to peak", discrete=TRUE,labels=scales::percent(seq(0, 1, 0.1)+0.1)) +theme_ipsum_rc(grid="") +theme(panel.spacing.y=unit(-0.05, "lines"),strip.text.y = element_text(hjust=0, angle=360),axis.text.y=element_blank(),axis.text.x = element_text(angle = 45, hjust = 1, vjust = 1))
