I attached data file of n*4 size. I used
[idx,C] = kmeans(X,3)
for clustering and obtain idx as cluster index and C as centroid, but I want to plot which shows these three clusters. how to do it.

The documentation for kmeans gives several examples of plotting the output (including the code to do so).

in Documentation cluster plotting given only for 2 variable, but I have 4 variable data so I don't know how to do it for 4 variable

It is of course not possible to plot four spatial dimensions. The main alternatives would all involve plotting some projection of your data onto a smaller number of dimensions. Possibilities are
  • Use plot3 or scatter3 to plot 3 out of 4 dimensions, each in turn
  • Just use plot as in the example, and plot each pair in turn
