Making plot for clusters in K means clustering

[sdhilip]

Hi

I am doing K-Means clustering in SAS Guide. I have 8950 observations and 21 variables. I chose 6 clusters, but unable to get proper cluster plot. Below my code. Please advise

proc fastclus data=cluster maxclusters=6 out =  clust;
var BALANCE--PAYMENT_MINPAY;
run;

proc sort;
by cluster distance;
run;

proc print;
by Cluster;
run;

proc freq data=work.clust; tables cust_id*cluster / nocol nopercent; run;

proc candisc out = can; 
class cluster; 
var BALANCE	--PAYMENT_MINPAY;
run;

proc sgplot data = can; 
title "Cluster Analysis for Bank datasets"; 
scatter y = can2 x = can1 / group = cluster; run;

I chose K = 6 randomly. Anyone can suggest how to choose K in K Means clustering at SAS. I check the elbow method for selecting clusters in Python. No idea how to do it SAS? I am getting good cluster graph for the same dataset in Python.
