add new series in XY charts

[User (Legacy)]

Hi,

I need to add new series in XY chart dynamically. Each series may have

different numbers of data.  For example, series 1 has 100 points with range

from 1 to 100, series 2 has 1000 points with range from 500 to 1000.  And I

have to load the data of next series after all previous series were

displayed. All series of data should go in the same chart.

I loaded the data of series 1 using the code as follows:

 m_pChartFX->OpenDataEx(COD_VALUES,1,100);

 m_pChartFX->OpenDataEx(COD_XVALUES,1,100);

 m_pChartFX->Series->Item[0]->Yvalue[0] = 1;

 m_pChartFX->Series->Item[0]->Yvalue[1] = 45;

 m_pChartFX->Series->Item[0]->Yvalue[2] = 60;

.....

 m_pChartFX->Series->Item[0]->Xvalue[0] = 10;

 m_pChartFX->Series->Item[0]->Xvalue[1] = 21;

 m_pChartFX->Series->Item[0]->Xvalue[2] = 32;

 ....

 m_pChartFX->CloseData((CfxCod) (COD_XVALUES|COD_SMOOTH));

  m_pChartFX->CloseData(COD_VALUES);

It works fine. But when I tried to load the XY pair of data of series 2 in

m_pChartFX->Series->Item[1],  I got the abnormal program termination error.

Is any propery I should set to load the unknow number of series? Or what

should I do before I can load the second series of data?

Thanks,

Before you try accesing the second series (m_pChartFX->Series->Item[1]) you

must do:

m_pChartFX->OpenDataEx(COD_VALUES,2,100);

 m_pChartFX->OpenDataEx(COD_XVALUES,2,100);
