scatter plot of neural network

hello i want to plot my neural network out of patternent function

to a scatter plot where the scattered points are clustered according to the classes which the are .I have lots of classes in my data like 40 and 50 classes.

Okay what's the question? You have scatter to plot. You got data.

[Newman]

This is the plot i have taken from a paper .I dont know how to code it in matlab for lets say 10 or 50 classes. Each point in the plot must indicate one sample of the testing database used for classification.

What data you have for the 10-50 classes? Is it (x,y) ?

What is the dimensionality of your original data?

[Newman]

Hi my original data is a 96x96 image . But i have applied pca and reduced its dimension to somewhere around 40-60 principle components. I have 200 images in the testing set.
