# Ruby/PGPLOT example: pgline

### code

    require 'pgplot'
    include Pgplot

    n = 100
    x = NArray.sfloat(n).indgen!/10
    y = NMath.sin(x)

    pgopen                 # open PGPLOT session
    pgenv 0, n/10, -1, 1   # set "Plotter Environment" and draw box.
    pglab "x", "y", "PGPLOT Example: y = sin(x)"
    pgsci 2                # set Color Index = Red.
    pgslw 5                # set Line Width.
    pgline x, y            # plot Line.
