Description

Attach an Origin C Curve object to an internal Origin Y data set and its associated X data set.

Attach an Origin C Curve object to internal Origin X and Y data sets.

Attach an Origin C Curve object to internal Origin X and Y datasets.

Attach a Dataset object to a worksheet column identified by worksheet name and column number.

Attach a Dataset object to a worksheet column identified by a Column object.

Syntax

BOOL Attach( LPCSTR lpcszYData )

BOOL Attach( LPCSTR lpcszXData, LPCSTR lpcszYData )

BOOL Attach( Worksheet & wks, int nColX, int nColY )

BOOL Attach( Worksheet & wks, int nColY )

BOOL Attach( LPCSTR lpcszWksName, int nCol )

BOOL Attach( Column & col )

Parameters

lpcszYData: [input] Name of Y Dataset

lpcszXData: [input] Name of X Dataset
lpcszYData: [input] Name of Y Dataset

wks: [input] Origin C Dataset object attached to an internal Origin worksheet
nColX: [input] 0 based offset or column number of X column (data set)
nColY: [input] 0 based offset or column number of Y column (data set)

wks: [input] Origin C Dataset object attached to an internal Origin worksheet
nColY: [input] 0 based offset or column number of Y column (data set)

lpcszWksName: [input] Name of worksheet in which column resides
nCol: [input] Origin C column number to attach to (nCol=1 attaches to second column in worksheet)

col: [input] Origin C column object attached to an Origin worksheet column

Return

Returns TRUE on successful exit and FALSE on error.

Examples

EX1

    return 0;
}

EX5

int Curve_Attach_ex5(string wksName = "Book1")
{
    // Datasets Book1_A and Book1_B must exist prior to execution
    Curve    crv;               // Create unattached Curve object

        for(int ii = 0; ii < 10; ii++)
            crv[ii] = -ii;
    }
    return 0;
}

EX6

void Curve_Attach_ex6()
{
    // Worksheet columns Book1_A and Book1_B must exist prior to execution
    Column colB("Book1",1);    // Create an Origin C Column object attached to the second column
                               // in the Origin worksheet Book1
    Curve    crv;              // Create unattached Dataset object
    crv.Attach(colB);          // Attach Dataset object to first column in Data1 worksheet
}

Remark

Attach an Origin C Dataset object to an Origin worksheet column identified by an Origin C Column object. Origin C Dataset objects must be attached to internal Origin data sets either by constructor or by the Attach method.
