Create and combine quiver and contour plots

Im trying to figure out how to create and combine a quiver plot and a contourf using 4 vectors. I already have the quiver plot done but im stuck on the contourf. What i keep getting with the countourf is:
Error using contourf (line 61)
Z must be at least a 2x2 matrix.
Error in Importingshit (line 9)
contourf(x,y,vx,vy);
For the time being im just trying to get the contourf to work but if someone is willing to help me combine them then i would deffinitly not refuse. Thanks in advance!

You’re calling contourf wrong. It doesn’t use the ‘vx’ and ‘vy’ (that I assume you use in your quiver plot). It wants a single square matrix ‘z’, or ‘x’, ‘y’, ‘z’ matrix arguments. See the documentation for it for details.

What are the sizes of x and y?
What is the surface you want to plot? It has to be a matrix, and ideally a function of matrices X and Y. The surface Z must be some function of X and Y if you give it all three arguments.
We don’t have your data or code, so we’re purely guessing here.
