From the matching chart, you can have a global picture about the duplicates in the analyzed data.

The Hide groups less than parameter, which is set to 2 by default, enables you to decide what groups to show in the result chart. Usually you want to hide groups of small group size.

For example, the above matching chart indicates that:
  • 48 items are analyzed and classified into 18 groups according to a given match rule and after excluding items that are unique, by setting the Hide groups less than parameter to 2.

  • 11 groups have 2 items each. In each group, the 2 items are duplicates of each other.

  • 3 groups have 3 items each. In each group, these items are duplicates of one another.

  • 3 groups have 4 items each. In each group, these items are duplicates of one another.

  • One single group has 5 duplicate items.
