plt.figure(0)? why 0
plt.scatter(X[:,0],X[:,1]) means??
Doubt in kmeans cluster
Hi @silpasweta,
In plt.figure(0) here 0 is the unique number of this particular figure, if this is left empty, every time a new figure is created with the number increment. So, Basically this is optional parameter.
plt.scatter(X[:,0],X[:,1]) the first parameter X[:,0] means we are considering all the values/rows of first column (index 0) on X-axis, and X[:,1] means taking all the values/rows from second column index(1) on Y axis. and we are scattering these values on 2 axis.
I hope this clears your doubt
