Markers
Markers are symbols used to identify the individual data values, i.e., the x and y coordinates intersection on a chart. Area, line, and scatter charts can all use markers.
Properties
| Property | Description |
|---|---|
| Color | Gets or sets the color of the Marker. |
| Size | Gets or sets the size of the Marker. |
Marker Symbols
Markers can be created for the following symbols.
| Symbol | Method | Description |
|---|---|---|
| Asterisk | GetAsterisk(Single) | Gets the instance of the Marker type as an Asterisk. |
| Circle | GetCircle(Single) | Gets the instance of the Marker type as a Circle. |
| Cross | GetCross(Single) | Gets the instance of the Marker type as a Cross. |
| Dash | GetDash(Single) | Gets the instance of the Marker type as a Dash. |
| Diamond | GetDiamond(Single) | Gets the instance of the Marker type as a Diamond. |
| Plus | GetPlus(Single) | Gets the instance of the Marker type as a Plus. |
| Square | GetSquare(Single) | Gets the instance of the Marker type as a Square. |
| Triangle | GetTriangle(Single) | Gets the instance of the Marker type as a Triangle. |
Adding Markers
The following code illustrates adding a marker to a DateTimeLineSeries.
DateTimeLineSeries lineSeries = new DateTimeLineSeries("Series name");
Marker marker = Marker.GetCircle(2);
lineSeries.Marker = marker;
Dim MyLineSeries As DateTimeLineSeries = New DateTimeLineSeries("Series name")
Dim MyMarker As Marker = Marker.GetCircle(2)
MyLineSeries.Marker = MyMarker
The Series class can also add markers using its constructors. The following example illustrates adding markers to an XYScatterSeries using one of its constructors.
XYScatterSeries xyScatterSeries1 = new XYScatterSeries("Team A", Marker.GetPlus(5));
XYScatterSeries xyScatterSeries2 = new XYScatterSeries("Team B", Marker.GetTriangle(10));
Dim MyXyScatterSeries1 As XYScatterSeries = New XYScatterSeries("Team A", Marker.GetPlus(5))
Dim MyXyScatterSeries2 As XYScatterSeries = New XYScatterSeries("Team B", Marker.GetTriangle(10))
