I have a vector field whose function I do not know. It is just a list of coordinates along with the corresponding i and j vectors for each coordinate. This is my gradient vector field. I would like to find and draw the contours of the function whose gradient this is, and I know that contours are orthogonal to the gradient vectors. How can I do this? Just to be clear, I do NOT know the actual function whose vector field I have, I only have the vector field itself from data I have collected elsewhere.
As of now I am just using ListVectorPlot to show my field.
