The attributes that define how a series of data looks in the scatter plot are called a Chart3DStyle. Each series has its own Chart3DStyle, which can be customized. The Chart3DStyle object allows the following properties of a series to be changed programmatically:
•The LineStyle property, which defines the line style for the object. This specifies the color, pattern, and thickness of drop lines.
•The SymbolStyle property, which defines the symbol style for the object. This specifies the color, size and shape of points.
The Chart3DStylesCollection contains the Chart3DStyle objects defined for each series. The following methods are defined for the Chart3DStylesCollection:
Method | Description |
AddNewStyle() | Add a new ChartStyle object to the collection. |
Remove(index) | Remove a ChartStyle object from the collection. |
Normally, manual adding or removing of Chart3DStyle objects from the collection is not needed. If a Chart3DStyle object already exists when its corresponding series is created, the previously created Chart3DStyle object is used to display the data in this series.
Looping through the Chart3DstylesCollection can quickly change the behavior of all of the lines or points in a chart. For example, the following code lightens all of the points in a chart whenever the mouse is clicked:
Private Sub C1Chart3D1_Click(ByVal sender As Object,
ByVal e As System.EventArgs) Handles C1Chart3D1.Click
Dim Style As Chart3DStyle
For Each Style in Chart3D1.ChartGroups.ChartStyles
Style.SymbolStyle.Color = Color.White
Next Style
End Sub
•C#
private void c1Chart3D1_Click(object sender, System.EventArgs e)
{
foreach(Chart3DStyle sty in c1Chart3D1.ChartGroups.ChartStyles)
sty.SymbolStyle.Color = Color.White;
}
Setting the line pattern
The following sets the line pattern for the second series to a dotted line:
C1Chart3D1.ChartGroups.ChartStyles(1).LineStyle.Pattern = LinePatternEnum.Dot
•C#
C1Chart3D1.ChartGroups.ChartStyles[1].LineStyle.Pattern = LinePatternEnum.Dot;
Setting the symbol style
And the following statement sets the symbol style for the third series to an unfilled circle:
C1Chart3D1.ChartGroups.ChartStyles(2).SymbolStyle.Shape = SymbolShapeEnum.Circle
•C#
C1Chart3D1.ChartGroups.ChartStyles[2].SymbolStyle.Shape = SymbolShapeEnum.Circle;
Formatting data point symbols
You can easily format the Scatter Plot's data point symbols shape, size, color, and width using the properties of the Chart3DSymbolStyle class.
Use the Symbol Shape property to set the symbol type, the Size property to set its size, and the Color properties to set the symbol color for a ChartStyle. The valid types of symbols are shown below:
