Examples

The following code example demonstrates how to use the ChartObjects method to get the collection of embedded charts and a single embedded chart. The example first uses the ChartObjects method to get the Microsoft.Office.Interop.Excel.ChartObjects collection of the current worksheet and create a new Microsoft.Office.Interop.Excel.ChartObject. After formatting the new Microsoft.Office.Interop.Excel.ChartObject and giving the Microsoft.Office.Interop.Excel.ChartObject a name, the example then uses the ChartObjects method to get the new Microsoft.Office.Interop.Excel.ChartObject (indexed by its name) and displays a print preview of the chart.

This example is for a document-level customization.

Private Sub CreateAndPreviewChart()
    Me.Range("A1", "A3").Value2 = 11
    Me.Range("B1", "B3").Value2 = 55

    Dim ChartObjects1 As Excel.ChartObjects = _
        CType(Me.ChartObjects(), Excel.ChartObjects)
    Dim chartObject1 As Excel.ChartObject = _
        ChartObjects1.Add(100, 20, 400, 250)

    chartObject1.Chart.ChartWizard(Me.Range("A1", "B3"), _
        Excel.XlChartType.xl3DColumn, Title:="New Chart")
    chartObject1.Name = "NewChartObject" 

    Dim chartObject2 As Excel.ChartObject = _
        CType(Me.ChartObjects("NewChartObject"), Excel.ChartObject)
    chartObject2.Chart.PrintPreview(False)
End Sub

private void CreateAndPreviewChart()
{
    this.Range["A1", "A3"].Value2 = 11;
    this.Range["B1", "B3"].Value2 = 55;

    Excel.ChartObjects ChartObjects1 =
        (Excel.ChartObjects)this.ChartObjects();
    Excel.ChartObject chartObject1 = ChartObjects1.Add(100, 20, 400, 250);

    chartObject1.Chart.ChartWizard(this.Range["A1", "B3"],
        Excel.XlChartType.xl3DColumn, "New Chart");
    chartObject1.Name = "NewChartObject";

    Excel.ChartObject chartObject2 =
        (Excel.ChartObject)this.ChartObjects("NewChartObject");
    chartObject2.Chart.PrintPreview(false);
}
