Apr 21, 2020 · The matplotlib.pyplot.contour() are usually useful when Z = f(X, Y) i.e Z changes as a function of input X and Y. A contourf() is also available which allows us to draw filled contours. Syntax: matplotlib.pyplot.contour([X, Y, ] Z, [levels], **kwargs) Parameters: X, Y: 2-D numpy arrays with same shape as Z or 1-D arrays such that len(X)==M and ...
