Color | A Color expression that indicates the color of the bar. The last 7 bits in the high significant byte of the color indicates the identifier of the skin being used to paint the bar. Use the Add method to add new skins to the control. The skin object is used to draw the bar in the chart area. |
The following properties may be used to change the color for a particular bar:
If the bar's Pattern is exPatternBox, the Color property indicates the color to show the bar's frame. In the same context, the StartColor and EndColor properties indicates the color to show the bar in gradient.
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 StartColor property to specify the color for the beginning part of the bar, if the StartShape property is not exShapeIconEmpty. Use the EndColor property to specify the color for the ending part of the bar, if the EndShape property is not exShapeIconEmpty.
In VB.NET or C# you require the following functions until the .NET framework will provide:
Shared Function ToUInt32(ByVal c As Color) As UInt32 Dim i As Long i = c.R i = i + 256 * c.G i = i + 256 * 256 * c.B ToUInt32 = Convert.ToUInt32(i) End Function
private UInt32 ToUInt32(Color c) { long i; i = c.R; i = i + 256 * c.G; i = i + 256 * 256 * c.B; return Convert.ToUInt32(i); }
The following VB sample creates a new bar called "Task2", that's similar with the "Task" bar excepts that we change the color to fill the bar:
With G2antt1.Chart.Bars With .Copy("Task", "Task2") .Color = RGB(255, 0, 0) End With End With
The following C++ sample creates a new bar called "Task2", that's similar with the "Task" bar excepts that we change the color to fill the bar:
CBars bars = m_g2antt.GetChart().GetBars(); CBar bar = bars.Copy( "Task", "Task2" ); bar.SetColor( RGB(255,0,0) );
The following VB.NET sample creates a new bar called "Task2", that's similar with the "Task" bar excepts that we change the color to fill the bar:
With AxG2antt1.Chart.Bars With .Copy("Task", "Task2") .Color = ToUInt32(Color.Red) End With End With
The following C# sample creates a new bar called "Task2", that's similar with the "Task" bar excepts that we change the color to fill the bar:
EXG2ANTTLib.Bar bar = axG2antt1.Chart.Bars.Copy("Task", "Task2"); bar.Color = ToUInt32(Color.Red);
The following VFP sample creates a new bar called "Task2", that's similar with the "Task" bar excepts that we change the color to fill the bar:
with thisform.G2antt1.Chart.Bars with .Copy("Task", "Task2" ) .Color = RGB(255,0,0) endwith endwith
