Plot Bar Graph

Add a bar plot to an exiting ggplot plot object. Graphical choices were made to closely reflect plots generated with LBoM::monthly_bar_graph and LBoM::weekly_bar_graph.

Usage

iidda_plot_bar(
  plot_object,
  data = NULL,
  series_variable = NULL,
  time_unit = "month_factor_abbr"
)

Arguments

plot_object

a ggplot2 plot object

data

data frame containing data prepped for bar plotting, typically output from iidda_prep_bar(). If NULL data is inherited from plot_object

series_variable

column name of series variable in data, default is "deaths"

time_unit

time unit to display bar graphs on the x-axis. Defaults to "week" or one of iidda.analysis:::time_units that starts with "month". Should generalize at some point to be able to take any time_unit argument.

Value

a ggplot2 plot object containing a bar graphs of time series data
