I am plotting some vector plots with the ListVectorPlot function with VectorColorFunction being "Rainbow". What I want is to scale the colorbar as per my requirements so that I can get varied colour for different values of vector magnitude. How to incoprorate this into my code? I am writing the part of my code with ListVectorPlot.
streamData = Table [ { datax[[i, n - j + 1]], datay[[i, n - j + 1]]}, {i, 1, m}, {j, 1, n}];
ListVectorPlot [ streamData, StreamPoints -> 250, Frame -> False, VectorPoints -> All, Axes -> True, VectorColorFunction -> "Rainbow"];
Thanks in advance.
