2.2.4.7 DataObjectBase

Name

DataObjectBase

Remark

The DataObjectBase class provides methods and properties common to all data objects. The Origin C DataObjectBase class is an abstract base class used for polymorphic handling of DataObject and DataPlot related class types. Consequently, Origin C objects of type DataObjectBase can not be constructed. Derived classes such as DataObject, Column, MatrixObject, and DataPlot inherit DataObjectBase class methods and should be used instead.

EX1

void DataObjectBase_ex1()
{
    Worksheet wks;
    wks.Create("origin");
 
    if(wks)
    {
        int nCol = wks.Columns("B").GetIndex();
        string strNewColName;
        if(nCol >=0) 
            wks.InsertCol(nCol+1, "Result", strNewColName);
    }
}

Reference

Members

Name	Brief	Example
	Retrieves categorical map from DataObject.
	A DataObjectBase object is always associated with a dataset inside Origin. Since Dataset is a template class, we use the name as the common mean of connecting to a Dataset.
	Get the index of object in layer, 0 offset.
	It retrieves the data (display) range for the object.
	It sets the data (display) range for the object.

Property

Name	Brief	Example
	Property: The lower data range index for the object.
	Property: The upper data range index for the object.
	Property: For Column or DataPlot that has been set with SetEvenSampling, the X value of the 1st row. NANUM if not applicable.
	Property: For Column or DataPlot that has been set with SetEvenSampling, the X increment between each row. NANUM if not applicable.
