Question about graphing the clusters in K means I've used K means to cluster my data. Before using K means, I had used StandardScaler on my data to standardize the data. Now, I'm wondering how can I show the clusters of the original data. Scikit-learn gives the labels on the standardized data but I want to have the labels on the original data and show the clusters of the original data on the graph.
StandardScaler subtracts the mean from each variable and then divides it by the standard deviation. It's a common preprocessing step, certainly for k-means because this algorithm heavily depends on the scaling of the data. 

If I understand correctly you want to visualize the original data and make use of the labels from k-means by doing so. You could either add the labels to the original data (assuming the order of the records did not change):

original_with_label = numpy.concatenate(original, labels, axis = 1)


Or you could transform the data back to its original scale:

transformed_back_to_original = scalar_fit.inverse_transform(transformed_data)
