Default

In R, we use do.call to constructs and executes a function call from a name or a function and a list of arguments to be passed to it.

do.call(
  n_scatter,
  n_options(
    default = common_settings,
    data = data[data$group == "girls low", ],
    x = "x",
    y = "y",
    group = "group" # use group column for series name
  )
)

Multiple Series

do.call(
  n_scatter,
  n_options(
    default = common_settings,
    data = data,
    x = "x",
    y = "y",
    group = "group"
  )
)

Alternative colors

do.call(
  n_scatter,
  n_options(
    default = common_settings,
    data = data,
    x = "x",
    y = "y",
    group = "group",
    colors = list(
      scheme = "category10"
    )
  )
)

Using Time Scales

data <- data.frame(
  group = c(rep("apple", 8), rep("oranges", 8)),
  x = rep(seq.Date(as.Date("2018-01-01"), by = "days", length.out = 8), 2),
  y = c(7, 5, 11, 9, 12, 16, 13, 13, 14, 14, 15, 11, 10, 12, 9, 7)
)
reactable(data)

settings <- n_options(
  default = common_settings,
  data = data,
  x = "x",
  y = "y",
  group = "group",
  xScale = list(
    type = "time",
    format = "%Y-%m-%d",
    precision = "day"
  ),
  xFormat = "time:%Y-%m-%d",
  axisBottom = list(
    format = "%b %d",
    tickValues = "every 2 days"
  )
)

do.call(n_scatter, settings)

Using Logarithmic Scales

data <- data.frame(
  name = "apples",
  x = c(10, 100, 1000, 10000, 100000, 1000000),
  y = c(2, 4, 8, 16, 32, 64)
)

settings <- n_options(
  default = common_settings,
  data = data,
  x = "x",
  y = "y",
  group = "name",
  xScale = list(
    type = "log",
    base = 10
  ),
  xFormat = NA,
  yScale = list(
    type = "log",
    base = 2
  ),
  yFormat = NA,
  axisBottom = list(
    tickValues = c(10, 100, 1000, 1000, 10000, 100000, 1000000, 10000000)
  ),
  axisLeft = list(
    tickValues = c(2, 4, 8, 16, 32, 64)
  )
)

do.call(n_scatter, settings)
