matplotlib cm.get_cmap(name, num_steps)

My python code uses

plt.cm.getcmap("coolwarm", num_steps)

This causes a deprecation warning.

The get_cmap function was deprecated in Matplotlib 3.7 and will be removed in 3.11. Use matplotlib.colormaps[name] or matplotlib.colormaps.get_cmap() or pyplot.get_cmap() instead.

however - both suggested methods do not provide a "num_steps" parameter. How do I need to update my statement to be compatible?

Solution 
  • In [29]: import matplotlib
    ...: 
    ...: cw = matplotlib.colormaps['coolwarm']
    ...: cw10 = matplotlib.colormaps['coolwarm'].resampled(10)
    ...: print(cw.N, cw10.N)
256 10
