X Y {Z} <flag>
Syntax:
set table {"outfile" | $datablock} {append} {separator {whitespace|tab|comma|"<char>"}} plot <whatever> unset table
Subsequent tabular output is written to "outfile", if specified, otherwise it
is written to stdout or other current value of set output. If outfile
exists it will be replaced unless the append keyword is given.
Alternatively, tabular output can be redirected to a named data block.
Data block names start with '$', see also inline data (p. ). You must explicitly
unset table in order to go back to normal plotting on the current terminal.
The separator character can be used to output csv (comma separated value)
files. This mode only affects plot style with table. See plot with table (p. ).
