I'm not sure I know what you mean. Can you give an example?
ListVectorPlot is often confusing because it tries to smooth out data and show vectors at even intervals. It's very often the case that someone uses the function when they really don't want to be using that function.
Sometimes the answer is to use the option VectorPoints->All:

Sometimes it's easier to build your plot with Arrows and Graphics:
Graphics[{Arrowheads[0.02], Flatten@Table[ Arrow[{{x, y}, {x, y} + 0.1 {y, y}}], {x, -3, 3, 0.5}, {y, -3, 3, 0.5}]}, Axes -> True]
