Consistent vector length across plots using VectorPlot[ ]?

Hello,

I am plotting some 2D vector fields using VectorPlot. I want to be able to compare the field magnitude at different points visually, and color is not an option so scaling the vector lengths seems appropriate. This can be achieved with the VectorScaling option but the result is normalized over each plot. It looks like the older version VectorScale could do what I want (using sfun), but this has since replaced by VectorScaling which gives me less options.

It seems to me that what I am trying to do is very basic, but I can’t figure out how to do it. Does anyone have any ideas? This post https://mathematica.stackexchange.com/questions/14439/how-to-scale-vectors-in-vectorplot shows one way to do what I want with ListVectorPlot and the old VectorScale option.

Thanks in advance.

You should add the option VectorRange—Wolfram Documentation VectorRange. If you apply the same range for each plot it should be consistent.

Yes! This seems to work. I would never have guessed that’s what I needed to do. Thank you!
