NAME
isag - Interactive System Activity Grapher
SYNOPSIS
isag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd
gr_width]
DESCRIPTION
The isag command graphically displays the system activity data stored
in a binary data file by a previous sar run. The isag command invokes
sar to extract the data to be plotted.
The data are processed using sar command and slightly transformed to
tabular format, and then this format is visualized using gnuplot pro-
gram.

-ght gr_height

-gwd gr_width
Specify the width of the chart area. Default value is: 720.
CONFIG FILE

It seems useful, because new run doesn't need new settings to obtain
same scale.
