Plot the per-date delay profiles

One translucent curve per date (see by) giving that date's share of reports at each delay, coloured by its mean delay. A batch is a lone right-shifted (long-delay) curve.

Usage

plot_delay_profiles(
  x,
  by = c("report", "event"),
  max_delay = NULL,
  plotly = FALSE,
  axis = c("report", "revision"),
  linewidth = 1,
  palette = .tbl_now_palette()
)

Arguments

x

A tbl_now() object.

by

One line per "report" date (default) or per "event" date.

max_delay

Largest delay to draw. NULL (default) caps at the delay covering 99% of reported mass.

plotly

If TRUE, return an interactive plotly widget instead of a static plot. Default FALSE.

axis

Which time axis the delay is measured on: "report" (default) or "revision". Report-axis delays are measured from event to report; revision-axis delays are measured from report to revision, the same quantity as .revision_delay. Needs a revision process (see add_revision_date()); cases still "pending" are left out.

linewidth

Multiplier on the width of the per-date curves. Default 1 (drawn at 0.4). The curves are deliberately faint and overplotted – it is their envelope that carries the message – so raising this on a long series fills the panel in.

palette

A named colour palette (see tbl_now_palette()).

Value

A ggplot2 object (or a plotly widget when plotly = TRUE).

Examples

data(denguedat)
dn <- tbl_now(denguedat, onset_week, report_week, verbose = FALSE)
