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.

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.
A contour plot is a 2D diagram that uses circles (often colored) to represent the third axis. Any point on the circle has the same value in the third axis. Matplotlib makes it fairly simple to draw contour plots.
A contour plot can be created with the plt.contour function. It takes three arguments: a grid of x values, a grid of y values, and a grid of z values. The x and y values represent positions on the plot, and the z values will be represented by the contour levels.
30 maj 2023 · The Matplotlib provides two functions plt.contour, and plt.contourf to plot the contour plots. The contour() Method. The matplotlib.pyplot. contour() method is used to draw contour lines. It returns the QuadContourSet. Following is the syntax of this function – contour([X, Y,] Z, [levels], **kwargs) Parameters

Mixin to provide labelling capability to ContourSet. add_label (x, y, rotation, lev, cvalue) [source] # Add a contour label, respecting whether use_clabeltext was set.
