When table mode is enabled, plot and splot commands print out a
multicolumn text table of X Y {Z} R values rather than creating an actual
plot on the current terminal. The character R takes on one of three values:
"i" if the point is in the active range, "o" if it is out-of-range, or "u"
if it is undefined. The data format is determined by the format of the axis
tickmarks (see set format (p.
)), and the columns are separated by single spaces.
This can be useful if you want to generate contours and then save them for
further use. The same method can be used to save interpolated data
(see set samples (p.
) and set dgrid3d (p.
)).
Syntax:
set table {"outfile" | $datablock}
plot <whatever>
unset table
Tabular output is written to the named file, if any, otherwise it is written
to the current value of set output. Alternatively, tabular output can be
redirected to a named data block. Data block names start with '$', see also
inline data (p.
). You must explicitly unset table in order to go back to normal
plotting on the current terminal.
To avoid any style-dependent processing of the input data (smoothing,
errorbar expansion, secondary range checking, etc), or to increase the number
of columns that can be tabulated, you can use the keyword "table" instead of a
normal plot style. For example
set table
plot <file> using 1:2:3:4:5:6:7:8:9:10 with table
