  hline = NULL, x.interval = NULL, date.format = NULL, y.min = NULL,
  y.max = NULL, ribbon.lwr = NULL, ribbon.upr = NULL,
  legend.names = NULL, ribbon.names = NULL, aspect.ratio = 1.61, ...)

Arguments

data	data frame containing data for plotting
y	specifying column name in data that should be y variable
x	specifying column name in data that should be x variable
group	specifies the label for splitting data into multiple lines

sub.title	character string specifying chart sub title
x.title	character string specifying x-axis title
y.title	character string specifying y-axis title
vline	numeric specifying position of vertical line
hline	numeric specifying position of horizontal line
x.interval	numeric used to set number of breaks when scaling the x variable
date.format	character vector specifying the date label (see details)
y.min	numeric setting the minimum value on y-axis
y.max	numeric setting the maximum value on y-axis
ribbon.lwr	character string specifying column with values for lower ribbon
ribbon.upr	character string specifying column with values for upper ribbon
legend.names	character vector setting custom legend names
ribbon.names	character string specifying custom legend name for ribbon

Details

Format codes for time series classes are defined in strftime. If date.format is set to NULL the date format will be set to the most used format for each time series class.

The ellipsis is used to pass on arguments to the plot_theme function. Primary use is to specify the legend.position to either "left", "right", "bottom", "top" or "none". Arguments can also be sent to plot_theme function to adjust plot margins - see function for more details.
