Single Line Chart Example

# For Single line chart, let's focus on Bachelors or Higher Education level

Two Line Chart Example (Secondary Palette)

In this example we will try to plot two lines for comparision with a secondary color paletter

fig <- rural_urban_2021 %>%
  ggplot(aes(as.Date(date),
             pct_working_remotely,
             group = education_level,
             color = education_level)) +
  geom_line() +
  geom_point() +
  scale_x_date(date_breaks = "1 month", date_labels =  "%b") +
  scale_y_continuous(limit = c(NA, 0.16)) +
  ggtitle("Line Chart - straight lines") +
  labs(title = "",
       subtitle = "Only 2 Columns")+
  xlab("2021") +
  ylab("Percentage Working Remotely")+
