Arguments

df

Data frame

x_var

Required variable name for the variable containing the x-coordinates. Will be coerced to numeric with as.numeric.

y_var

Required variable name for the variable containing the y-coordinates. Will be coerced to numeric with as.numeric.

x_axis_label

Optional label for the x-axis, defaults to an empty string.

fill_var

Variable name for the discrete variable which determines the groups to be stacked, e.g. degree.

fill_label

Optional variable name for the character variable containing the names of the fill variable, defaults to NULL.

fill_reverse

Boolean indicating whether the order of the fill variable should be reversed, defaults to FALSE.

legend_reverse

Optional boolean indicating whether the legend should be reverted, defaults to FALSE.

facet_var

Optional variable name for the discrete variable to facet by, defaults to NULL.

title

Optional plot title

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 cutoff value for the suppression of data labels. By default, all values below 0.04 of the total value of the stacked bar chart are suppressed.

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

max_width_axis_text_y

Optional maximum width in characters for the text of the y axis.

max_width_strip_label

Optional maximum width in characters for the facet label passed to ggplot2::label_wrap_gen.

plot_width

Width of the plot in inches, defaults to 6.8

Value

A ggplot object
