How to use the ColorBand?

[Jerry]

Dear Steema support,

I want to add a colorband to my chart,my code as followed:

int m_nCurrentBand=GetTools().Add(tcColorband);
COleVariant colorBandAxis;
colorBandAxis.vt = VT_DISPATCH;
colorBandAxis.pdispVal = GetAxis().GetLeft().m_lpDispatch;
GetTools().GetItems(m_nCurrentBand).GetAsColorband().SetAxis(colorBandAxis);

but the error which says that an Invalid Axis type!



Any help will be appreciated!

Hi Jerry,

I've just tried the following code with TeeChart ActiveX v2012.0.0.9 in VB6 and it works without problems.

Code: Select all

  TChart1.Aspect.View3D = False
  TChart1.AddSeries scFastLine
  TChart1.Series(0).FillSampleValues
  TChart1.Tools.Add tcColorband
  With TChart1.Series(0).YValues
    TChart1.Tools.Items(0).asColorband.Axis = TChart1.Axis.Left
    TChart1.Tools.Items(0).asColorband.StartValue = .Minimum + (.Maximum - .Minimum) / 4
    TChart1.Tools.Items(0).asColorband.EndValue = .Minimum + (.Maximum - .Minimum) / 2
  End With

Are you using the latest TeeChart ActiveX version?
If you still have problems with it, could you please arrange a simple example project we can run as-is to reproduce the problem here?
