Hi, I am very new in using Mathematica and would appreciate some helps in ListPlotVectorField and related topics. I have three 2D text files of the same dimension: x.dat, y.dat, and w.dat. (each element in a row is separated by space, each row is ended by a return). I would like to use x.dat and y.dat as the components to draw a 2D map of line vectors, and would like to use w.dat to either control the width of the individual line vectors or the color of the individual line vectors. By reading help files, I think that I should use ListPlotVectorField[list], where list is the ?two-dimensional array of vectors¹. However, I could not find any information regarding the structure of this list. I appreciate if anyone knows (1) any information regarding the structure of this list, and how to use ListPlotVectorField (2) any hints on how to use my third data file w.dat to control the width or color or the line vector map. Thank you in advance. Yang Xia xia at oakland.edu
