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 select "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
           Dim s As Series
           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 = 60
                 .DataPoints.Item(-1).Marker.Style = VtMarkerStyleX
                 .DataPoints.Item(-1).Marker.Pen.VtColor.Red = 0
                 .DataPoints.Item(-1).Marker.Pen.VtColor.Blue = 0
                 .DataPoints.Item(-1).Marker.Pen.VtColor.Green = 0
              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.
