Draw a burndown chart

Plot a burndown chart.

Usage

# S4 method for burndown
plot(
  x,
  col = NULL,
  draw.plan = TRUE,
  draw.regression = TRUE,
  draw.lastupdate = FALSE,
  t.stop = "",
  y.name = "Remaining Effort",
  debug = FALSE,
  ...
)

Arguments

x

A burndown object.

col

list of colours for items, starting with the first key in the file (which will be at the bottom of the chart). If not specified, the hcl() scheme will be used, to generate colours that are distinct, that show up reasonably well on a monitor.

draw.plan

boolean, set to TRUE to draw the plan, as a blue descending line with a horizontal intercept.

draw.regression

boolean, set to TRUE to draw a red dashed line indicating the overall progress, as determined by regression.

draw.lastupdate

boolean, set to TRUE to draw the last update (which otherwise requires a sharp eye).

t.stop

a POSIX time, the maximum time for graph (defaults to deadline if not given).

y.name

character string, for labelling the vertical axis.

debug

boolean, set to TRUE to monitor the work.

...

extra things handed down to plotting functions.
