Adding Data to real time charts

[User (Legacy)]

Hi, 

I am using the ChartFX 98 component in Visual C++.  I am having problems 

adding data using the series object but it works fine using ValueEx 

property.  Also, I can't seem to align my scrollbar to display the last 

point that was added to the chart.  In the code below I have included the 

calls I am making when I am trying to align the scrollbar. 

Help is greatly appreciated. 

Here is my code: 

This works.......... 

//add one point from the right in realtime for each series 

m_spChartFX->OpenDataEx((CfxCod) (COD_VALUES | COD_ADDPOINTS), m_numSeries, 

1); 

 for (short i = 0; i < m_numSeries; i++) { 

      m_spChartFX->ValueEx[i][0] = rand() % 100; 

 } 

 // Closing the data channel using COD_SMOOTH will stop screen flickering 

 m_spChartFX->CloseData((CfxCod) (COD_VALUES | COD_REALTIME | COD_SMOOTH | 

COD_REALTIMESCROLL)); 

 m_spChartFX->Scroll(CSB_RIGHT, 0); 

This does not work..... 

 ICfxSeriesEnumPtr seriesEnumPtr = m_spChartFX->GetSeries(); 

//add one point from the right in realtime for each series 

m_spChartFX->OpenDataEx((CfxCod) (COD_VALUES | COD_ADDPOINTS), m_numSeries, 

1); 

 for (short i = 0; i < m_numSeries; i++) { 

      ICfxSeriesPtr seriesPtr = seriesEnumPtr->GetItem(i); 

     seriesPtr->PutYvalue(0, rand() % 100); 

      //m_spChartFX->Series->Item[m_traceVariables[i]->item]->PutYvalue(0, 

rand() % 100); 

 } 

 // Closing the data channel using COD_SMOOTH will stop screen flickering 

 m_spChartFX->CloseData((CfxCod) (COD_VALUES | COD_REALTIME | COD_SMOOTH | 

COD_REALTIMESCROLL)); 

 m_spChartFX->Scroll(CSB_RIGHT, 0); 

Thanks
