Value on the x axis.

y

groups

Name of the column containing the different groups.

faceted

If TRUE (default), each group will be plotted separately.

scales

From ggplot2::facet_wrap: Should scales be 'fixed', 'free', or free in one dimension ('free_x', 'free_y'). Default is 'fixed'.

show_trend

If TRUE, adds a ggplot2::geom_smooth() line to the plot. Default is FALSE.

y_axis_label

Label for the y axis.

plot_palette

Character vector of hex codes specifying the colors to use on the plot.

plot_palette_generator

Palette from the viridis package, used in case plot_palette is unspecified or insufficient for the number of colors required.

scatterplot_title

Title of the scatter plot section on the report. If NULL, chronicle will try to parse a generic title using make_title()

title_level

Level of the section title of this plot (ie, number of # on Rmarkdown syntax.)

echo

Whether to display the source code in the output document. Default is FALSE.

message

Whether to preserve messages on rendering. Default is FALSE.

warning

Whether to preserve warnings on rendering. Default is FALSE.
