dear experiences

i have dataset which has been clusters using k-means and stored in an excel file (clu.xlsx) , my data consist from 200 observations where :

first column is observation labels second column is x data values third columns is y data values fourth columns is cluster ids ( 1,2,3...K "clustering has done using k-means") and : cent= stored the centroids of my clusters

my question :

- how do i can plot observation in scatter plot where i would like colored every points in cluster with different colors from other in other clusters.
- then how to plot centroids also.

thanks for any suggestion

Hi. How can I use gscatter for 3D scatter plots? I know the function scatter3, but unfortunately the function gscatter3 DOESN'T exist. Could you help me please?
