cloudUtilPlot: Cloud Utilization Plot

Description

On the utilization graphic each horizontal line indicates the start and the end of one job. Color groups different runs.

Usage

cloudUtilPlot(group, begin, end, id,  	colormap, 
	normalize, 
	plotConcurrent, 
	plotConcurrentMax, 
	main)

Arguments

begin

a time series of the starting events; the time format is unix time stamp (seconds since Jan 01 1970).

end

a time series of the corresponding ending events.

id

identifyer of each event.

group

group of each event.

main

an overall title for the plot.

colormap

color vector for the data. default is the rainbow colormap having as much colors as we have groups.

normalize

normalizes the time in a way that the groups are relative to each other; default is set to TRUE.

plotConcurrent

plot concurrent running tasks as solid lines; default is set to TRUE.

plotConcurrentMax

plot maximum of concurrent running tasks; default is set to FALSE.

Details

The cloudUtilPlot function reqires the four arguments begin, end, group, and id. All other arguments are optional.
