I'm having trouble getting it working in MSC++.

I've used the code from the VB demo,

Private Sub Form_Load()
  TChart1.AddSeries scLine
  TChart1.AddSeries scLine
  
  TChart1.Series(0).FillSampleValues (10)
  TChart1.Series(1).FillSampleValues (10)
  
  TChart1.Series(0).Color = RGB(130, 155, 254)
  TChart1.Series(1).Color = RGB(252, 209, 36)
  
  TChart1.Tools.Add tcSeriesBand
  
  With TChart1.Tools.Items(0).asSeriesBand
    .Series = TChart1.Series(0)
    .Series2 = TChart1.Series(1)
    .Gradient.EndColor = RGB(128, 0, 128)
    .Gradient.Visible = True
    .Pen.Visible = True
    .Pen.Width = 5
    .Pen.Color = vbRed
  End With
End Sub

and in C++, I've got

Code: Select all

            CToolList tools = pTChart->GetTools();
            tools.Add(tcSeriesBand);

            tools.GetItems(0).GetAsSeriesBand().SetSeries((VARIANT&)*pseries);

            tools.GetItems(0).GetAsSeriesBand().GetGradient().SetVisible(pRow->m_LineBorderSettings.m_bVisible);
            tools.GetItems(0).GetAsSeriesBand().GetGradient().SetEndColor(pRow->m_LineBorderSettings.m_Colour);
            tools.GetItems(0).GetAsSeriesBand().GetGradient().SetMidColor(pRow->m_LineBorderSettings.m_Colour);
            tools.GetItems(0).GetAsSeriesBand().GetGradient().SetStartColor(pRow->m_LineBorderSettings.m_Colour);

            tools.GetItems(0).GetAsSeriesBand().GetPen().SetVisible(pRow->m_LineBorderSettings.m_bVisible);
            tools.GetItems(0).GetAsSeriesBand().GetPen().SetWidth(pRow->m_LineBorderSettings.m_nWidth);
            tools.GetItems(0).GetAsSeriesBand().GetPen().SetColor(pRow->m_LineBorderSettings.m_Colour);
            tools.GetItems(0).GetAsSeriesBand().GetPen().SetEndStyle(pRow->m_LineBorderSettings.m_nPenEndStyle);
            tools.GetItems(0).GetAsSeriesBand().GetPen().SetStyle(pRow->m_LineBorderSettings.m_nPenEndStyle);

            tools.GetItems(0).GetAsSeriesBand().GetPen().SetSmallSpace(pRow->m_LineBorderSettings.m_nSpace);

The line

tools.GetItems(0).GetAsSeriesBand().SetSeries((VARIANT&)*pseries);

always causes a crash. I've tried

Code: Select all

tools.GetItems(0).GetAsSeriesBand().SetSeries(*pseries);

but that will not compile (cannot convert from CSeries to VARIANT).

Any ideas?

Hi TonyVSUK,

First of all I'd like to apologise for the delayed reply.

What about doing as in the example here? Following what's in this example you can do this:

Code: Select all

	long series1;
	series1 = m_Chart1.AddSeries(scLine);

	CToolList tools = m_Chart1.GetTools();
    tools.Add(tcSeriesBand);

	tools.GetItems(1).GetAsSeriesBand().SetSeries(COleVariant(series1));

I'm sure I tried that.

But I've moved on to something else now anyway.

Hello,

Didn't that work at your end? It works fine for me here.

I cannot remember. But it's definitely something I would have tried.

But like I said, I've moved onto something else.
