How do I plot a multidimensional array?

Question

I have a multi-dimensional array that is the centroid of Kmeans output. Its size is (10,6). I want to see the location of these centroids in a plot, but I do not know how can I plot them in a plane. I tried to add a cluster column to the array like this center['cluster']=clusterNumber and the clusterNumber is a float array that contains cluster number, but it produces an error:

IndexError: only integers, slices (`:`), ellipsis (`...`), NumPy.newaxis (`None`) and integer or boolean arrays are valid indices

Do you know what is the problem and how can I plot this multidimensional array? The centroid array is:

19.6135 19.8452 19.9962 20.1065 20.1966 20.2832
26.5262 29.6227 31.4583 32.7302 33.7162 34.6274

Answer 1

Looking at the shape of your array, it only makes sense that it has 10 or 6 centroids (depending on the logic of your code). That said, each of your centroids can only have 6 or 10 dimensions (again, depending on the logic of your code), and this is a problem, as our brain can only observe at most 3 dimensions. However, you can get an idea of how your centroids look like in 3 dimensions by applying a projection. Take a look at this question to get an idea of how to do that.
