lines

The lines style connects adjacent points with straight line segments. It may be used in either 2D or 3D plots. The basic form requires 1, 2, or 3 columns of input data. Additional input columns may be used to provide information such as variable line color (see rgbcolor variable).

2D form (no "using" spec)

   1 column:   y     # implicit x from row number
   2 columns:  x y

3D form (no "using" spec)

   1 column:   z     # implicit x from row, y from index
   3 columns:  x y z
