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.
