[SOLVED] Problem by Sorting the Results

Hi every body 
I have some problems about sorting the results. I have a classification problem with a polynomial class attribute (A, B, C, D, E, F,...)
There is no problem in classification process, but the classification performance operator produces an unsorted confusion matrix, i.e columns and rows are not in an alphabetical order and it looks like a random order (D, F, A, C, B, E, ...). I have the same problem when I use Plot View to produce bar charts and the order is not alphabetical.
Do you know what is wrong and how can I solve this problem?
Thanks a lot

Hi,
the problem here is that the internal nominal mapping of RapidMiner doesn't know anything about alphabetical ordering. In the following thread someone posted a solution to your problem: http://rapid-i.com/rapidforum/index.php/topic,5297.0.html
