histDisplay is an rtsh(1) script for extracting archived historical
data, previously archived using hist2csv(1), and displaying it in a
plot. This script assumes that the historical tables have not changed.
For example, the current item number for "AI 1024.current value" has
not changed in the history table.
The -p argument specifies the RTAP plot alias to use to display the
extracted historical data.
The -d argument specifies the date for which the archived historical
data is to be retrieved from.
The -h argument specifies the alias of the historical data to
retrieve.
The -P argument specifies the plot display name to use when displaying
the historical data. If this is not specified, RtapPlotDisp, will be
used.
The -i argument specifies the directory where the archived historical
files are kept. The default is the current working directory.
The -t argument specifies the title to use on the plot that is
displayed. The default is what was in the plot point.
The -n argument specifies the pen number to use. The default is pen
zero.
The -v flag indicates to print verbose messages to stdout.
histDisplay logs error messages to stdout.
