Ngraph(1) creating scientific 2-dimensional graphs

SYNOPSIS

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

DESCRIPTION

Ngraph is the program to create scientific 2-dimensional graphs for researchers and engineers. Graphs can be exported to PostScript, SVG, PNG or PDF format.

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 line width
-CR n
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)
