XYRangeComplex

Name

XYRangeComplex

Remark

The XYRangeComplex class provides methods to get and set complex type XY dataset for matrix and worksheet window. Same as DataRange class, itself does not hold data, just keep the data range with page name, sheet name and row/column indices. One XYRangeComplex object allow containing multiple sub XY complex data ranges.

The XYRangeComplex class is derived from the XYRange, DataRange class from which it inherits methods and properties.

Examples

EX1

// The function first creates a worksheet and puts some input data
// into it. Then it initializes XYRangeComplex such that it refers to the data
// in the worksheet.
// Then it creates the output worksheet, extracts the data from the input (i.e. source)
// worksheet using XYRangeComplex::GetData() method, and puts them into the output worksheet.
void    XYRangeComlex_ex1()

    // and set some complex values into it:
