Since Gri is still under development, some of these defaults might change, so you should not rely on them remaining the same. Presently, the defaults are equivalent to:
    set arrow size 0.2         # (cm)
    set axes style 0
    set beep off
    set clip off
    set clip postscript off
    set contour format %lg
    set contour label position ? ?
    set contour labels horizontal
    set contour labels whiteunder
    set dash off
    set font size 12           # (pt)
    set font to helvetica
    set graylevel 0            # Black ink
    set ignore initial newline off
    set input data window x off
    set input data window y off
    # Following set (curve, axes, symbol) widths to width
    # of rapidograph pens called (6x0, 3x0,  6x0)
    set line width 0.709        # (pt) for curves
    set line width axis 0.369   # (pt) for axes
    set line width symbol 0.369 # (pt) for symbols
    set missing value 1.0e22
    set page portrait
    set page factor 1
    set symbol size 0.1        # (cm)
    set tic size 0.2           # (cm)
    set tics out
    set trace off
    set x format %lg
    set x margin 6.0           # (cm)
    set x name "x"
    set x size 10              # (cm)
    set x type linear
    set y axis name vertical
    set y format %lg
    set y margin 6.0           # (cm)
    set y name "y"
    set y size 10              # (cm)
    set y type linear
(NOTE: Programmers may alter the gri source file ``defaults.h`' and then recompile Gri, if they feel the need to change these things. Also, see the file ``startup.c`' and the function ``gr_begin()`' in ``gr.c`'.)
