Vector Plot

Origin provides several types of 2D and 3D Vector graphs. A vector graph is a multidimensional graph used in industries such as meteorology, aviation, and construction that illustrates flow patterns (e.g. of wind, water, magnetic field), and represents both direction and magnitude at each point. See examples in the table below:

2D Vector Graphs

Vector plot illustrating the effect on river water flow of two differently shaped pylons. A color graph adds magnitude as a fourth dimension.

Options for 2D Vector Graphs:

  • Construct vectors from end-point data, XY/XY
  • Specify constant arrow-head size for vectors, or scale with magnitude
  • Adjust the vector length by specifying the magnitude multiplier
  • Adjust color and width of vectors
  • Connect vectors with line
  • Construct vectors from start-point, plus angle and magnitude, XY/AM

Options for 3D Vector Graphs:

  • Construct vectors from end-points, XYZ/XYZ
  • Adjust vector lengths with scaling factor
  • Adjust arrow head size with absolute or relative scaling
  • Adjust color and width of vectors
  • Draw projections onto any axis plane
  • Construct vectors from start-point plus increment, XYZ/dXdYdZ
