10.1: Defaults

At startup time, Gri sets the values of some things, like font size. 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'.)
