Our diagram looks rather overloaded, since there are too many small values in the diagram, which are invisible anyway. FastReport allows limiting the values number in a diagram by a predefined value. Thus, all the values, which do not belong the limit set, would be displayed as a single value, representing the sum of values, which did not fit the diagram.

In our example, the diagram has 18 values, and only 8 of them can be displayed. Let us enter the editor and set limiting:

The limiting will work if the "TopN" is nonzero. The name in the "TopN title," which will be displayed opposite to the sum value, should be specified. Sorting mode is not significant; values will be sorted by default.

As a result, the report will look as follows:
