Command synopsis

Listing 9 Synopsis of the plot command with default setup.

cmd = plot {
        sid                     = 1,     -- stream id 1 <= n <= 25 (Gnuplot instances)
        data            = nil,   -- { x=tbl.x, y=vec } (precedence over table)
        table           = nil,   -- mtable
        tablerange      = nil,   -- mtable range (default table.range)
        sequence        = nil,   -- seq | { seq1, seq2, ...,} | "keep"
        range           = nil,   -- sequence range (default sequence.range)
        name            = nil,   -- (default table.title)
        date            = nil,   -- (default table.date)
        time            = nil,   -- (default table.time)
        output          = nil,   -- "filename" -> pdf | number -> wid
        scrdump         = nil,   -- "filename"

        info            =nil,   -- information level (output on terminal)
        debug           =nil,   -- debug information level (output on terminal)
}

The plot command format is summarized in Listing 9, including the default setup of the attributes. The plot command supports the following attributes:

info

A number specifying the information level to control the verbosity of the output on the console. (default: nil). Example: info = 2.

A number specifying the debug level to perform extra assertions and to control the verbosity of the output on the console. (default: nil). Example: debug = 2.

The plot command returns itself.
