e_mark_point( e, serie = NULL, data = NULL, ..., title = NULL, title_position = NULL ) e_mark_line( e, serie = NULL, data = NULL, ..., title = NULL, title_position = NULL ) e_mark_area( e, serie = NULL, data = NULL, ..., title = NULL, title_position = NULL )
e |
An |
serie |
Serie or vector of series to mark on, defaults to all series. |
data |
Placement of point, line or area. |
... |
Any other option to pass, check See Also section. |
title |
A convenience argument to easily set label, see details. |
title_position |
Position of title. |
To set a label you need to either use the title
argument or pass a list specifying the label formatter.
label = list(formatter = "label"). The former is more convenient
but more limited, e.g.: you cannot specify the placement of the label.
