IChart.UndoRedo

Syntax

Description

The UndoRedo property determines parameters of the undo/redo stack in the chart.

Example

Executing the example requires a chart in a regular report with the REGULAR_REPORT identifier.

Add links to the Metabase, Chart, Report and Tab system assemblies.

Sub UserProc;
Var
    Report: IPrxReport;
    Sheet: IPrxSheet;
    PrxTable: IPrxTable;
    TabSheet: ITabSheet;
    Chart: IChart;
    MB: IMetabase;
    UndoRedo: IUndoRedo;
Begin
    // Get repository
    MB := MetabaseClass.Active;
    // Get chart in regular report
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    Sheet := Report.Sheets.Item(0);
    PrxTable := Sheet As IPrxTable;
    TabSheet := PrxTable.TabSheet;
    Chart := TabSheet.Objects.Item(0).Extension As IChart;
    // Get undo/redo stack of chart
    UndoRedo := Chart.UndoRedo;
    // Set availability and number of stack changes
    UndoRedo.Enabled:= True;
    UndoRedo.Limit:= 5;
    (Report As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the undo/redo stack is available for the chart; the number of available undo/redo operations is set to 5 operations.
