Input Parameters
| XW | Specifies the data channel containing the xw-values. |
| Y | Specifies the data channel containing the y-values. |
 [ChnEventBeginIndex] |
Specifies the line number from where DIAdem checks the values of the data channel. The default value is 0 which means that DIAdem checks the values from the first row. |
| [ChnEventEndIndex] |
Specifies the line number up to which DIAdem checks the values of the data channel. The default value is 0 which means that DIAdem checks the values up to the last row. |
| [ChnEventMaxResultCount] |
Specifies the maximum number of result values. The default value is 0 and means that DIAdem uses all result values. |
Return Parameters
| ReturnValue | A return value is a two-dimensional array containing the extended search results. Refer to Result of the Event Search for a detailed description of the array. Use the variables ChnEventList1, ChnEventList2, or ChnEventResultList as the return value of this function, or define your own variable. |
Examples
The following example searches for the areas in which the values of the [1]/[2] channel are invalid. As a result the example returns an Event/EventStatus channel which always contains the value 1, if the values of the second channel of the first group are invalid. Otherwise the result channel contains the value 0.
