Remarks

The Marker interface contains properties that allow you to specify the size (Marker.Size) and shape (Marker.Symbol) of data markers indicating each data point in the series.

An object exposing the Marker interface can be accessed via the Series.Marker property of a series object.

Examples

The example below demonstrates how to create a line chart with custom data markers. To access the Marker object, use the Series.Marker property, and then specify the shape (Marker.Symbol) and size (Marker.Size) of markers displayed at each data point in the series.

Dim worksheet As Worksheet = workbook.Worksheets("chartTask5")
workbook.Worksheets.ActiveWorksheet = worksheet

' Create a chart and specify its location.
Dim chart As Chart = worksheet.Charts.Add(ChartType.Line, worksheet("B2:C8"))
chart.TopLeftCell = worksheet.Cells("F2")
chart.BottomRightCell = worksheet.Cells("L15")

' Display markers and specify the marker style and size.
chart.Series(0).Marker.Symbol = MarkerStyle.Circle
chart.Series(0).Marker.Size = 15
' Hide the legend.
chart.Legend.Visible = False
