HOW TO USE
I=userdata(data);
data: A cell made up with string ONLY. Each column means a property or physical quantity. Each row means an example or case.
e.g.
data={'Peter' '180'; 'White' '190'} means Peter is 180cm tall and White is 190cm tall.
Notice: only string is allowed
I: A cell made up with frequency table. Each column is the same meaning with cell A. Each row is the string sorted by frequency descend.

WHAT DOES THIS PLOT MEAN
The picture is made up with some colurful rings. Each ring means a property in the cell A. Color means frequency and deeper color means higher frequency.
When the colour distributes randomly, the data is not in correlation, like figure 1 in example.m.
When two neighbouring rings share the same shape, the two properties of rings are good correlation, like figure 2 in example.m.

More explanation is to be published in a paper (To be done).
