The gradient function returns the gradient of a scalar function (in the 3-dimensional case) depending on z-values, which means the gradient is approximated. To get a better approximation it would be best to feed as much z-values into the gradient function as possible. The function returns a gradient vector for every z-value fed to the function. Wanting to visualize the gradient, this means that for higher resolution gradients a lot of vectors are generated, which can create cluttered visualization (i.e. figure 1, where the blue lines underneath the curve represent the gradient vectors).
