Scaling, Normalization, Min Max.
your scaled value for x would be: from mpl_toolkits.mplot3d import Axes3D df = pd.DataFrame({ 'x1': np.random.randint(-100, 100, 1000).astype(float), 'y1': np.random.randint(-80, 80, 1000).astype(float), 'z1': np.random.randint(-150, 150, 1000).astype(float), }) scaler = preprocessing.Normalizer()
