Plot contour lines. Call signature: contour( [X,Y,]Z,[levels],**kwargs) contour and contourf draw contour lines and filled contours, respectively. Except as noted, function signatures and return values are the same for both versions. Parameters: X, Yarray-like, optional. The coordinates of the values in Z.

21 kwi 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)
Learn how to generate contour plots quickly using Python/matplotlib with a dummy data set. See how to format your data, use meshgrid, and customize your plot with color and labels.

The contour command in matplotlib produces a plot where the contour levels are not filled. We might want a filled contour plot instead, so we can use the contourf ( f for filled ) function instead. We might also want a color bar to tell us the scale of the colors.
You can create contour plots in Matplotlib using the contour() function in the "matplotlib.pyplot" module. This function accepts X and Y coordinates as either 1D or 2D arrays, representing the grid on which the function "Z" is evaluated.
