Unable to retrieve X-Axis values. ?????

[User (Legacy)]

greetings- 

(I have a ChartFX98 control on my form. I am using BCB 5.0.) 

I am (still) having a problem recalling the data values for the x-axis. 

The first code snippet: 

    //{Open the VALUES channel and keep number of series and points} 

    ChartFX1->OpenDataEx(COD_VALUES | COD_SMOOTH ,COD_UNCHANGE, 

COD_UNCHANGE); 

    ChartFX1->ThisSerie = SeriesNum; 

    ChartFX1->Value[index] = ODValue; 

    ChartFX1->Xvalue[index] = (float)wavelength; 

    //{Close the VALUES channel} 

    ChartFX1->CloseData(COD_VALUES | COD_SMOOTH ); 

adds new values to my chart. SeriesNum indicates what series to place 

the values in. ODValue is the Y-axis values, wavelength is the X-Axis 

values. This works, and displays the chart appropriately. 

The second code snippet: 

    ICfxSeriesPtr pSeries; 

    float tempfloat,tempfloat2; 

    pSeries=ChartFX1->Series->get_Item(SeriesCount); // series count 

indicates what series I'm looking at 

    // 

    for (int i=0; i< ChartFX1->NValues; i++) 

        { 

        tempfloat = pSeries->get_Yvalue(i); 

        tempfloat2 = pSeries->get_Xvalue(i); 

        ResultsMemo->Lines->Add("recall btn value(x,y): " + IntToStr(i) 

+ " " + FloatToStrF(tempfloat2,ffFixed,5,3) + ", " + 

FloatToStrF(tempfloat,ffFixed,5,3)); 

        } 

this code is supposed to show the x,y value pairs in a memo. I ALWAYS 

get 0.0 for the tempfloat2 variable. 

can anyone give me an indication as to what I am doing wrong? ('cause it 

must be something!) 

thanks!
