NAME

Ngraph - 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)

-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)

-cg n: specify green component of the 2nd plot color (0-255)

-cb n: specify blue component of the 2nd plot color (0-255)

-s line: specify number of the head skip

-r step: specify number of the read step

-f line: specify number of the final line

-vx n: neighbor average of the x data

-vy n: neighbor average of the y data

-mx formula: specify math transformation for the x data

-my formula: specify math transformation for the y data

-ex {linear | log | inverse | MJD}: specify scale type of the x axis

-ey {linear | log | inverse | MJD}: specify scale type of the y axis

-minx value: specify minimum value of x axis

-maxx value: specify maximum value of x axis

-incx value: specify increment value of x axis

-miny value: specify minimum value of y axis

-maxy value: specify maximum value of y axis

-incy value: specify increment value of y axis

-g: load settings from data file

-png file: convert ngp file to PNG format

-pdf file: convert ngp file to PDF format

-ps file: convert ngp file to PostScript format

-eps file: convert ngp file to Encapsulated PostScript format

-svg file: convert ngp file to SVG format

-gra file: convert ngp file to GRA format

-dialog: show print dialog (with -p option)

-p file: print ngp file

-n: output ngp-file to stdout
