Pattern Property

Visual Basic
C#

'Declaration
 
Public Property Pattern As LinePattern

'Usage
 
Dim instance As LineProperties
Dim value As LinePattern
 
instance.Pattern = value
 
value = instance.Pattern

public LinePattern Pattern {get; set;}

The Pattern and Factor properties define the line by working together to define whether a certain pixel from the line should be drawn or not. The values of the LinePattern enumeration actually represent 16-bit integers whose bit pattern determines which fragments of a line will be drawn when the line is rasterized. Bit zero is used first. For example the value of SolidLine is all ones (0xFFFF). You can create you own patterns by simply setting the bits of the short integer value that you want the line to draw. Suppose for example that you want to draw a line having three empty pixels, then one black then three empty and so forth. The value you should pass to the LinePattern in this case is 0x8888 or in binary 1000100010001000. You must also set the Factor property to 1.

The following example shows how to accomplish this:

Visual Basic

Dim chart As Chart =  ChartControl.Charts.GetAt(0) 
Dim bar As BarSeries = CType(chart.Series.Add(SeriesType.Bar), BarSeries)

bar.Add(10, "Apples")
bar.Add(20, "Oranges")
bar.Add(30, "Bananas")
bar.Add(25, "Tomatoes")
bar.Add(29, "Cucumbers")

bar.Appearance.LineMode = AppearanceLineMode.Series
bar.BarBorder.Color = System.Drawing.Color.Black
bar.BarBorder.Pattern = CType(0x8888, LinePattern)
bar.BarBorder.Factor = 1

C#

Chart chart = ChartControl.Charts.GetAt(0);
BarSeries bar = (BarSeries)chart.Series.Add(SeriesType.Bar);

bar.Add(10, "Apples");
bar.Add(20, "Oranges");
bar.Add(30, "Bananas");
bar.Add(25, "Tomatoes");
bar.Add(29, "Cucumbers");

bar.Appearance.LineMode = AppearanceLineMode.Series;
bar.BarBorder.Color = System.Drawing.Color.Black;
bar.BarBorder.Pattern = (LinePattern)0x8888;
bar.BarBorder.Factor = 1;
