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.IsMultiline := True;
    ChartExLegend.ElementHorizontalAlignment := ChartLegendElementHorizontalAlignment.Left;
End Sub UserProc;

After executing the example, the external legend elements are aligned to the left and the long names of elements are arranged in multiple lines.

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.IsMultiline := True;
    ChartExLegend.ElementHorizontalAlignment := Prognoz.Platform.Interop.Chart.ChartLegendElementHorizontalAlignment.clehaLeft;
End Sub OnBeforeOpenReport;

After opening the report, the external legend elements are aligned to the left and the long names of elements are arranged in multiple lines.
