CountDuplicates

Declaration:	TIlabTrnDataSet.CountDuplicates: integer;
The function CountDuplicates counts all duplicates from the data set and returns their number. Please note that a data point (see TDataPoint) is regarded to be duplicate if both the x and the y coordinates are the same.

Hint:

The search for duplicate data points may fail if the x and y coordinates are rational numbers (due to rounding effects).
