plot.burndown {plan}R Documentation

Draw a burndown chart

Description

Plot a burndown object.

Usage

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

Arguments

x an object of class burndown, to be plotted.
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 descending line with a horizontal intercept.
draw.regression boolean, set to TRUE to draw a regression line of actual overall progress.
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.
