Thanks,

Hi Petar,

There is a demo of it in the VCL features demo that explains quite well the BigCandle purpose. We'll try to add it in the nexts ActiveX versions.
It says:

The Big-Candle series is a normal Candle (OHLC) financial series that
displays four "marks" showing the Open, High, Low and Close of
every candle point.
The intended use is to show few candle points at a time for better display
of candle prices.

Here is the VB6 code:

Code: Select all

Private Sub Form_Load()
  TeeCommander1.Chart = TChart1
   
  TChart1.Header.Text.Text = "Normal Candle (OHLC) series"
  TChart1.Legend.Visible = False
  TChart1.Aspect.View3D = False
  TChart1.AddSeries scCandle
  TChart1.Series(0).FillSampleValues 20
    
  TChart2.Header.Text.Text = "Big-Candle"
  TChart2.Legend.Visible = False
  TChart2.Aspect.View3D = False
  TChart2.AddSeries scBigCandle
End Sub


Private Sub TChart1_OnMouseMove(ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  Dim tmp As Integer
  TChart2.Series(0).Clear
  tmp = TChart1.Series(0).Clicked(X, Y)
  If tmp <> -1 Then
     With TChart1.Series(0).asCandle
       TChart2.Series(0).asCandle.AddCandle .DateValues.Value(tmp), .OpenValues.Value(tmp), .HighValues.Value(tmp), .LowValues.Value(tmp), .CloseValues.Value(tmp)
    End With
  End If
End Sub

It would look like follows:

Hi Petar,

I've just added the missing example in the TeeChart AX new features demos. It will be available in the next maintenance release.
