WithEvents CalculateChart As Microsoft.Office.Tools.Excel.Chart
Private Sub DisplayWhenCalculated()
Me.Range("A1", "A5").Value2 = 22
Me.Range("B1", "B5").Value2 = 55
CalculateChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
"CalculateChart")
CalculateChart.SetSourceData(Me.Range("A1", "B5"), _
Excel.XlRowCol.xlColumns)
CalculateChart.ChartType = Excel.XlChartType.xl3DColumn
' This will raise the Calculate event.
Me.Range("A1").Value2 = 11
End Sub
Sub CalculateChart_Calculate() Handles CalculateChart.Calculate
MsgBox("The chart plotted new data.")

private void DisplayWhenCalculated()
{
this.Range["A1", "A5"].Value2 = 22;
this.Range["B1", "B5"].Value2 = 55;
Microsoft.Office.Tools.Excel.Chart chart1 =
this.Controls.AddChart(this.Range["D2", "H12"],
"chart1");
chart1.SetSourceData(this.Range["A1", "B5"],
Excel.XlRowCol.xlColumns);
chart1.ChartType = Excel.XlChartType.xl3DColumn;
chart1.Calculate +=
new Excel.ChartEvents_CalculateEventHandler(
chart1_Calculate);
