Hi, suppose i have a data set x:
x = [0,2,9,2,5,8,7,3,1,9,4,3,5,8,10,0,1,2,9,5,10] ;
figure(1)
[n,b] = hist(x)
bar(b,n) ;
use above code i can plot the distribution. Is there anyway that i can remove the points that occur less than others, for example, remove the data that occur less than 2 times in the array.
thank you

x = [0,2,9,2,5,8,7,3,1,9,4,3,5,8,10,0,1,2,9,5,10] ;
ii=unique(x)
[aa,bb] = hist(x,ii)
idx=aa>=2
bar(bb(idx),aa(idx))
