Examples

library(dplyr, warn.conflicts = FALSE)
data("biomedicalrevenue")
data("revenue_wide")

line_chart(revenue_wide, year, Roche)

line_chart(revenue_wide, year, Roche, line_size = 1.5)

line_chart(revenue_wide, year, Roche, line_color = "darkorange")

## Plot multiple lines (data is in long format)
biomedicalrevenue %>%
  filter(company %in% c("Roche", "Novartis", "Bayer")) %>%
  line_chart(year, revenue, group = company)

## Plot multiple lines (data in wide format, i.e. one column per line)
## Select multiple columns with `c()`
line_chart(revenue_wide, year, c(Roche, Novartis, Bayer))

## Select all columns from Novartis to Sanofi suing `:`
line_chart(revenue_wide, year, Novartis:Sanofi)

## Select all columns starting with "B"
line_chart(revenue_wide, year, starts_with("B"))
