VC++ annotations not working

Recommended Posts

Hello.

 

I'm trying to add an annotation to my chart using VC++, but they are not showed at all on the chart.

 

I'm using this code snippet (VC++) using COM interface... m_chartPtr is the chart instance which is rendering perfect.

 

  Cfx62ClientServerAnnotation::_AnnotationXPtr annotx;      HRESULT rs = annotx.CreateInstance(__uuidof(Cfx62ClientServerAnnotation::AnnotationX));      if (rs == S_OK)      {        annotx->Enabled = TRUE;        Cfx62ClientServerAnnotation::_AnnotationTextPtr text;        rs = text.CreateInstance(__uuidof(Cfx62ClientServerAnnotation::AnnotationText));        annotx->List->Add(text);        if (rs == S_OK)        {          text->Attach(Cfx62ClientServerAnnotation::StringAlignment::StringAlignment_Near, 2, Cfx62ClientServerAnnotation::StringAlignment::StringAlignment_Far, 62);          text->TextColor = RGB(255, 0, 0);          text->Text = "Sample text";          text->Color = m_chartPtr->ColorFromArgb(0, 0, 0, 0);          text->Border->Color = m_chartPtr->ColorFromArgb(0, 0, 0, 0);          text->Orientation = 0;          text->Align = Cfx62ClientServerAnnotation::StringAlignment::StringAlignment_Far;          text->LineAlignment = Cfx62ClientServerAnnotation::StringAlignment::StringAlignment_Near;          text->Top = 40;          text->Left = 40;          rs = text->SizeToFit();          if (rs == S_OK)          {            VARIANT v;            V_VT(&v) = VT_DISPATCH;            V_DISPATCH(&v) = annotx;            m_chartPtr->Extensions->Add(v);          }        }      }

 

Is the code wrong?

 

Any help will be really appreciated!

 

Regards!
