Re: marker Positioning

Steve,

Here's a way to annotate your chart using VB.  

Make sure you set a reference to the Annotation Extension.

Private Sub Form_Load()

   Dim obj As ChartFX

   Dim AnnotX As AnnotationX

   Dim c As AnnCircle

   Dim i As Integer, j As Integer

   Dim strAttach As String

   'set reference to chart object on the form

   Set obj = Me.ChartFX1.Object

   'instanciate the annotation object

   Set AnnotX = New AnnotationX

   'turn off toolbar (unless you want it on)

    Annotx.Toolbar = False

   'add AnnotX to chart obj

   obj.AddExtension AnnotX

   'add an annotation circle

   Set c = AnnotX.Add(OBJECT_TYPE_CIRCLE)

   'turn off series point markers

   obj.MarkerShape = MK_NONE

   'pick you point to mark

   i = 0 'series

   j = 7 'point index

   'size the circle

   c.Width = 10

   c.Height = 10

   'set attach coordinates

   strAttach = CStr(j + 1) & "," & CStr(obj.ValueEx(i, j))

   c.Attach ATTACH_CENTER, CStr(strAttach)

   'what good is it without color

   c.BkColor = obj.Series(i).Color  'back color

   c.Color = obj.Series(i).Color    'border color

   Set c = Nothing

   Set obj = Nothing

End Sub
