IChartExternLegend.RowCount

Fore Syntax

RowCount: Integer;

Fore.NET Syntax

RowCount: System.Int32;

Description

The RowCount property determines the number of rows of the chart external legend.

Comments

To use the RowCount property, set the ItemPlacement property to ChartExtLegPlacement.CustomRows.

The specified number of rows is always used regardless of the legend size. The number of columns is automatically calculated depending on the number of elements of the external legend and its size.

Fore Example

To execute this example, create a regular report with a chart and an external legend on the report sheet. A module is to be added to the report and the UserProc procedure is called from this module using the hyperlink. The inspector of module assemblies should contain links to the Chart, Report, Tab system assemblies.

Sub UserProc;
Var
    ChartExLegend: IChartExternLegend;
Begin
    ChartExLegend := (PrxReport.ActiveReport.ActiveSheet As IPrxTable).TabSheet.Objects.Item(1) As IChartExternLegend;
    ChartExLegend.ItemPlacement := ChartExtLegPlacement.CustomRows;
    ChartExLegend.RowCount := 5;
End Sub UserProc;

After executing the example five rows are used to display elements in the external legend.

Fore.NET Example

To execute this example, create a regular report with a chart and an external legend on the report sheet. The .NET assembly is added to the report to handle report events. The OnBeforeOpenReport event is described in the module of the specified assembly in the EventsClass class. Add links to the Chart and Tab system assemblies.

Imports Prognoz.Platform.Interop.Report;
Imports Prognoz.Platform.Interop.Chart;
Imports Prognoz.Platform.Interop.Tab;
...

Public Override Sub OnBeforeOpenReport(Report:IPrxReport; Var Cancel:Boolean);
Var
    ChartExLegend: IChartExternLegend;
Begin
    Cancel := False;
    ChartExLegend:=(Report.ActiveSheet As IPrxTable).TabSheet.Objects.Item[1] As IChartExternLegend;
    ChartExLegend.ItemPlacement := ChartExtLegPlacement.celpCustomRows;
    ChartExLegend.RowCount := 5;
End Sub OnBeforeOpenReport;

Opening the report sets five rows to display elements in the external legend.
