Cmap – Using this parameter, we can give colour to our graph. We can choose the colour from the below options. Interpolation – Different types of graphs can be created. WitrynaMatplotlib does this mapping in two steps, with a normalization from the input data to [0, 1] occurring first, and then mapping onto the indices in the colormap. Normalizations are classes defined in the matplotlib.colors () module. The default, linear normalization is matplotlib.colors.Normalize ().
