expression.BeginObject(id)
expression Required. An expression that returns a ChChartDraw object.
id Required Long. Set this argument to a unique identifier that will subsequently be used to identify the object being drawn. Set to -1 to identify the ChChartDraw object that has been passed into an event procedure.
Remarks
You can combine multiple drawing elements into a single user-selectable item by placing them between calls to the BeginObject and EndObject methods.
Example
This example uses the BeforeRender event to cancel the drawing of the gridlines and the plot area of the first chart in Chartspace1. The AfterRenderEvent then replaces the plot area with an ellipse that is drawn after the chart is rendered.
Private Sub ChartSpace1_BeforeRender(chartObject, Cancel)
Select Case TypeName(chartObject)
Case "ChGridlines"
' Cancel the drawing of the gridlines.
Cancel.Value = True
Case "ChPlotArea"
' Cancel the drawing of the plot area.
Cancel.Value = True
End Select
End Sub
Private Sub ChartSpace1_AfterRender(drawObject, chartObject)
Dim chConstants
Set chConstants = ChartSpace1.Constants
' Check to see if the chart has been rendered.
If TypeName(chartObject) = "ChChart" Then
' The next three lines of code set the interior
' and border properties of the ellipse.
drawObject.Interior.SetPresetGradient _
chConstants.chGradientHorizontal, _
chConstants.chGradientVariantStart, _
Int((24 - 1 + 1) * Rnd + 1)
drawObject.Border.Weight = 1
drawObject.Border.Color = "black"
' Begin the drawing object.
drawObject.BeginObject 1
' Draw the ellipse.
drawObject.DrawEllipse chartObject.PlotArea.Left, chartObject.PlotArea.Bottom, _
chartObject.PlotArea.Right, chartObject.PlotArea.Top
drawObject.EndObject
End If
End Sub
