Examples

The following code example inserts the number 16 to cells E1 through E3 and the number 24 to cells F1 through F3. The code then creates a Chart control to the top of the worksheet and passes cells E1 through F3 to the SetSourceData method to populate the chart with data.

Private Sub ExcelAddChart()
    Me.Range("E1", "E3").Value2 = 16
    Me.Range("F1", "F3").Value2 = 24

    Dim Chart1 As Microsoft.Office.Tools.Excel. _
        Chart = Me.Controls.AddChart(0, 0, 130, _
        130, "Chart1")

    Chart1.SetSourceData(Me.Range("E1", "F3"), _
        Excel.XlRowCol.xlColumns)
    Chart1.ChartType = Excel.XlChartType. _
        xlColumnClustered

End Sub

private void ExcelAddChart()
{
    this.Range["E1", "E3"].Value2 = 16;
    this.Range["F1", "F3"].Value2 = 24;

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(0, 0, 130, 130, "chart1");

    chart1.SetSourceData(this.Range["E1", "F3"], Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xlColumnClustered;
}
