Plot grouped line chart (figure type 4)

Usage

rub_plot_type_4(
  df,
  x_var,
  x_var_label = NULL,
  x_axis_label = "",
  y_var,
  y_axis_label = "",
  group_var,
  group_label = NULL,
  caption = "",
  caption_prefix = "Quelle:",
  filter_cutoff = 5,
  facet_var = NULL,
  color = RUB_colors["blue"],
  palette_reverse = FALSE,
  base_family = get_font_df()[["family"]],
  base_size = 11
)

Arguments

df: Data frame
x_var: Required variable name for the variable containing the discrete x-coordinates.
x_var_label: Optional variable name for the character variable containing the names of the x variable, defaults to NULL.
x_axis_label: Optional label for the x-axis, defaults to an empty string.
y_var: Required variable name for the variable containing the y-coordinates. Will be coerced to numeric with as.numeric.
y_axis_label: Optional label for the y-axis, defaults to an empty string.
group_var: Variable name for the discrete variable which determines the groups forming one line, e.g. degree_id.
group_label: Optional variable name for the character variable containing the names of the group variable (e.g. degree_txt), defaults to NULL.
caption: Optional character containing the data source for the figure (prefix 'Quelle:' is automatically added).
caption_prefix: Optional character containing the prefix for the caption, defaults to 'Quelle:'.
filter_cutoff: Optional integer marking the cutoff below which all value labels are suppressed, defaults to 5.
facet_var: Optional variable name for the discrete variable to facet by, defaults to NULL.
color: Color for font and borders, defaults to RUB_colors["blue"], i.e. #003560.
palette_reverse: Optional boolean indicating whether the colors in the palette should be reversed, defaults to FALSE.
base_family: base font family, defaults to RubFlama
base_size: base font size, defaults to 11

Value

A ggplot2 object
