Read in your data as a table named T, then follow this demo
ID = 1;
rowIdx = T.ID == ID;
plot(T.Z(rowIdx), T.dist(rowIdx))
You can plot something like this:
A = [1 2 10
1 3 10
1 5 10
2 2 10
2 3 10
2 5 10
3 2 10
3 3 10
3 5 10] ;
plot(A(A(:,1)==1,2),A(A(:,1)==1,3)) % this plot points with ID 1
You can also plot all at once using gscatter. You can put class as ID.
