NAME¶

Ngraph - creating scientific 2-dimensional graphs

SYNOPSIS¶

ngraph [options] [data file(s) or ngp file]

DESCRIPTION¶

OPTIONS¶

Command line options are:

-L file

load ngp file

-x column

data column for the x axis

-y column

data column for the y axis

-X

use X axis as the x axis

-Y

use Y axis as the y axis

-U

use U axis as the x axis

-R

use R axis as the y axis

-d {mark | line | polygon | curve | diagonal | arrow | rectangle | rectangle_fill | rectangle_solid_fill | errorbar_x | errorbar_y | staircase_x | staircase_y | bar_x | bar_y | bar_fill_x | bar_fill_y | bar_solid_fill_x | bar_solid_fill_y | fit}

specify plot type

-m type

specify mark type (0-89)

specify red component of the 1st plot color (0-255)

-CG n

specify green component of the 1st plot color (0-255)

-CB n

specify blue component of the 1st plot color (0-255)

-cr n

specify red component of the 2nd plot color (0-255)

-cg n
