Examples

The following code example demonstrates a handler for the Calculate event that displays a message box when the source data of the current Microsoft.Office.Tools.Excel.ChartSheetBase changes.

Private Sub DisplayCalculations()
    Globals.Sheet1.Range("A1", "A5").Value2 = 22
    Globals.Sheet1.Range("B1", "B5").Value2 = 55

    Me.SetSourceData(Globals.Sheet1.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    Me.ChartType = Excel.XlChartType.xl3DColumn

    ' This will raise the Calculate event.
    Globals.Sheet1.Range("A1").Value2 = 11
End Sub

Sub ChartSheet1_Calculate() Handles Me.Calculate
    MsgBox("The chart sheet plotted new data.")
End Sub

private void DisplayCalculations()
{
    Globals.Sheet1.Range["A1", "A5"].Value2 = 22;
    Globals.Sheet1.Range["B1", "B5"].Value2 = 55;

    this.SetSourceData(Globals.Sheet1.Range["A1", "B5"],
        Excel.XlRowCol.xlColumns);
    this.ChartType = Excel.XlChartType.xl3DColumn;

    this.Calculate +=
        new Excel.ChartEvents_CalculateEventHandler(
        ChartSheet1_Calculate);

    // This will raise the Calculate event.
    Globals.Sheet1.Range["A1", missing].Value2 = 11;
}

void ChartSheet1_Calculate()
{
    MessageBox.Show("The chart sheet plotted new data.");
}
