MORE INFORMATION

The following section demonstrates how to create a sample project that
modifies properties of Markers on an MSChart control.

Step-by-Step Example
--------------------

1. Start a new Standard EXE project. Form1 is created by default.

2. Click Components on the Project menu, and then check "Microsoft Chart
   Control."

3. Add an MSChart control and a CommandButton to Form1.

4. Set the ChartType property of the MSChart control to
   3- vtChChartType2dLine.

5. Add the following code to Form1:

      Option Explicit
      Private Sub Command1_Click()
         Dim x As Integer, y As Integer

         MSChart1.RowCount = 10
         MSChart1.ColumnCount = 4

         For y = 1 To 4
            MSChart1.Column = y
            For x = 1 To 10
                MSChart1.Row = x
                MSChart1.Data = x * y
            Next x

            With MSChart1.Plot.SeriesCollection.Item(y)
               'The next line is required to change the Marker properties.
               .SeriesMarker.Auto = False
               .DataPoints.Item(-1).Marker.Visible = True
               .DataPoints.Item(-1).Marker.Size = 20
               .DataPoints.Item(-1).Marker.Style = VtMarkerStyleStar
               .DataPoints.Item(-1).Marker.FillColor.Automatic = False
               .DataPoints.Item(-1).Marker.FillColor.Set 0, 0, 255
            End With

         Next y
      End Sub

6. Press the F5 key to run the project.

7. Click Command1. Note that the Marker style and size do not change.
