# It's as easy as this
AirPassengers %>%
  ts_as_tbl() %>%
  time_ggplot(time, value)

# And this
EuStockMarkets %>%
  ts_as_tbl() %>%
  time_ggplot(time, value, group)

# Converting this to monthly averages

EuStockMarkets %>%
  ts_as_tbl() %>%
  mutate(month = year_month_decimal(time)) %>%
  summarise(avg = mean(value),
            .by = c(group, month)) %>%
  time_ggplot(month, avg, group)

# zoo example
x.Date <- as.Date("2003-02-01") + c(1, 3, 7, 9, 14) - 1
x <- zoo::zoo(rnorm(5), x.Date)
x %>%
  ts_as_tbl() %>%
  time_ggplot(time, value)
