The example is a macro containing implementation of:
The method importing data using user algorithm. During import, the array that contains two data columns is obtained. There are symbolic values in the first column and random real numbers in the range from 0 to 100 in the second.
The property determining advanced settings in the XML format for user data provider or data consumer.
