Remarks

Use this class to limit pivot table rows and/or columns. All rows or columns that exceed specified limit are grouped into special 'other' group (default label is '...'). If underlying pivot table uses grouped labels (several dimensions for rows/columns) several 'other' groups may be produced to show correct values inside groups.

Examples

Copy

PivotTable originalPvtTbl;
var topPvtTbl = new TopPivotTable(originalPvtTbl, 
    10 /* top 10 rows */, 
    Int32.MaxValue /* no limit for columns */ );
