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 cells A1 through C8 and passes cells E1 through F3 to the SetSourceData method to populate the chart with data.

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

    Dim Chart1 As Microsoft.Office.Tools.Excel.Chart _
        = Me.Controls.AddChart(Me.Range("A1", "C8"), _
        "Chart1")

    Chart1.SetSourceData(Me.Range("E1", "F5"), _
        Excel.XlRowCol.xlColumns)
    Chart1.ChartType = Excel.XlChartType. _
        xlColumnClustered

End Sub

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

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["A1", "C8"], "Chart1");

    chart1.SetSourceData(this.Range["E1", "F5"], Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xlColumnClustered;
}
