Marker Interface
Represents a data marker displayed at each data point in the series on the line, scatter or radar chart.
Namespace: DevExpress.Spreadsheet.Charts
Assembly: DevExpress.Spreadsheet.v19.1.Core.dll
Declaration
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.
Example
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.
Note
A complete sample project is available at https://github.com/DevExpress-Examples/winforms-spreadsheet-chart-api-e5222
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
