By default, the StartShape property is exShapeIconEmpty. If the StartShape property is exShapeIconEmpty the bas has no starting part. Use the Color property to specify the color to fill the middle part of the bar. Use the Pattern property to specify the brush being used to fill the bar. Use the Shape property to specify the height and the vertical alignment of the middle part of the bar. Use the AddShapeCorner method to add a custom icon to be used as a starting or ending part of the bar. Use the Images or ReplaceIcon method to update the list of control's icons. 

The following VB sample adds a custom shape and defines a bar like this :

With G2antt1.Chart.Bars
    .AddShapeCorner 12345, 1
    With .Add("Task2")
        .Pattern = exPatternDot
        .Shape = exShapeThinDown
        .StartShape = 12345
        .StartColor = RGB(255, 0, 0)
        .Color = .StartColor
    End With
End With

The following C++ sample adds a custom shape and defines a bar like above:

CBars bars = m_g2antt.GetChart().GetBars();
bars.AddShapeCorner( COleVariant( (long)12345 ), COleVariant( (long)1 ) );
CBar bar = bars.Add("Task2");
bar.SetPattern( 2 /*exPatternDot*/ );
bar.SetShape( 20 /*exShapeThinDown*/ );
bar.SetStartShape( 12345 );
bar.SetStartColor( RGB(255, 0, 0) );
bar.SetColor( bar.GetStartColor() );

The following VB.NET sample adds a custom shape and defines a bar like above:

With AxG2antt1.Chart.Bars
    .AddShapeCorner(12345, 1)
    With .Add("Task2")
        .Pattern = EXG2ANTTLib.PatternEnum.exPatternDot
        .Shape = EXG2ANTTLib.ShapeBarEnum.exShapeThinDown
        .StartShape = 12345
        .StartColor = RGB(255, 0, 0)
        .Color = .StartColor
    End With
End With

The following VB.NET sample adds a custom icon to the start of all Task bars:

With AxG2antt1.Chart.Bars
    .AddShapeCorner(12345, 1)
    .Item("Task").StartShape = 12345
    .Item("Task").StartColor = UInteger.MaxValue
End With

The following C# sample adds a custom shape and defines a bar like above:

axG2antt1.Chart.Bars.AddShapeCorner(12345, 1);
EXG2ANTTLib.Bar bar = axG2antt1.Chart.Bars.Add("Task2");
bar.Pattern = EXG2ANTTLib.PatternEnum.exPatternDot;
bar.Shape = EXG2ANTTLib.ShapeBarEnum.exShapeThinDown;
bar.StartShape = (EXG2ANTTLib.ShapeCornerEnum)12345;
bar.StartColor = ToUInt32(Color.FromArgb(255, 0, 0));
bar.Color = bar.StartColor;

The following C# sample adds a custom icon to the start of all Task bars:

EXG2ANTTLib.Bars bars = axG2antt1.Chart.Bars;
bars.AddShapeCorner(12345, 1);
bars["Task"].StartShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconEmpty + 12345;
bars["Task"].StartColor = 0xFFFFFFFF;

The following VFP sample adds a custom shape and defines a bar like above:

With thisform.G2antt1.Chart.Bars
	.AddShapeCorner(12345, 1)
	With .Add("Task2")
	    .Pattern = 2 && exPatternDot
	    .Shape = 20 && exShapeThinDown
	    .StartShape = 12345
	    .StartColor = RGB(255, 0, 0)
	    .Color = .StartColor
	EndWith
EndWith

The following VB sample defines a new bar that looks like this :

With G2antt1.Chart.Bars.Add("Task2")
    .Pattern = exPatternShadow
    .Color = RGB(0, 0, 255)
    .StartShape = exShapeIconCircleDot
    .StartColor = RGB(255, 0, 0)
End With

The following C++ sample defines a bar that looks like this above:

CBar bar = m_g2antt.GetChart().GetBars().Add("Task2");
bar.SetPattern( 3 /*exPatternShadow*/ );
bar.SetColor( RGB(0, 0, 255) );
bar.SetStartShape( 4 /* exShapeIconCircleDot*/ );
bar.SetStartColor( RGB(255, 0, 0) );

The following VB.NET sample defines a bar that looks like this above:

With AxG2antt1.Chart.Bars.Add("Task2")
    .Pattern = EXG2ANTTLib.PatternEnum.exPatternShadow
    .Color = RGB(0, 0, 255)
    .StartShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconCircleDot
    .StartColor = RGB(255, 0, 0)
End With

The following C# sample defines a bar that looks like this above:

With AxG2antt1.Chart.Bars.Add("Task2")
    .Pattern = EXG2ANTTLib.PatternEnum.exPatternShadow
    .Color = RGB(0, 0, 255)
    .StartShape = EXG2ANTTLib.ShapeCornerEnum.exShapeIconCircleDot
    .StartColor = RGB(255, 0, 0)
End With

The following VFP sample defines a bar that looks like this above:

with thisform.G2antt1.Chart.Bars.Add("Task2")
	.Pattern = 3 && exPatternShadow
	.Color = RGB(0, 0, 255)
	.StartShape = 4 && exShapeIconCircleDot
	.StartColor = RGB(255, 0, 0)
EndWith
