A program for plotting two-dimensional vector fields

vfplot is a software for plotting 2D vector fields.

Main features:

  • Large arrows:
  • The idea of vfplot is to plot vector fields with relatively large arrows — large enough to be perceived individually
  • Curvy:
  • For large arrows to accurately represent the field they need to follow it in their shape; vfplot uses simple circular arcs
  • Placed apart:
  • Placement of large arrows on a regular grid would limit the dynamic range possible; vfplot places the arrows via a packing of their bounding ellipses
  • Field input:
  • Fields can be specified by data in a number of formats: a simple ASCII grid format, Gerris gfs files, or a pair of GMT grd files. Several test fields are built in and adding another is straightforward if you have a little C experience
  • Vector output:
  • Output is in the PostScript format which can be converted to SVG, PDF and other vector formats with standard tools. The files are small, typically a few tens of kilobytes
  • Limited in scope:
  • The vfplot program plots only arrows, it will not be a general purpose plotting program
  • Free software:
  • Released under the GNU GPL v3, contact the author for other licencing
