[output]the Y-independent data

vx

[output]the X independent data

pvError

[output]optional output of Y Error data

nIndex

[input]the data index

dwRulesEx

Examples

EX1

// This example assumes a worksheet with three columns is the active layer.
// Output the the data size of the Y column.
void XYRange_GetData_Ex1()
{
    Worksheet wks;
    wks= Project.ActiveLayer();
    XYRange dr;
    if( wks )
    {
        dr.Add(wks, 0, "X");
        dr.Add(wks, 1, "Y");
        dr.Add(wks, 2, "ED");
        
        DWORD dwRules = DRR_BAD_WEIGHT_TREATMENT;
        int nIndex = 0;
        vector vX, vY, vErr;
        if (dr.GetData(vY, vX, &vErr, nIndex, dwRules))
