IChart.AutoRotateMarker

Fore Syntax

AutoRotateMarker: Boolean;

Fore.NET Syntax

AutoRotateMarker: boolean;

Description

The AutoRotateMarker property determines whether a chart contains the auto rotation of marker.

Comments

To use the AutoRotateMarker property, set the IChartMarker.MarkerType property to TriangleUp/TriangleDown/Rhombus or select the marker type Triangular/Inverse triangular/Diamond on the charts:

Linear.
Scatter.
Radar.
Stepped.

Depending on the value change of the chart line series, the marker rotation angle changes dynamically.

Fore Example

Executing the example requires a regular report with the REGULAR_REPORT identifier that contains a line chart with two data series and markers as a triangle.

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

Sub UserProc;
Var
    Mb: IMetabase;
    Report: IPrxReport;
    Sheet: ITabSheet;
    Chart: IChart;
Begin
    // Get current repository and regular report
    Mb := MetabaseClass.Active;
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    // Get report chart
    Sheet := (Report.Sheets.Item(0) As IPrxTable).TabSheet;
    Chart := Sheet.Objects.Item(0).Extension As IChart;
    Chart.Series.DefaultSerie.ResetInheritance(ChartSeriePropertyInheritance.AutoRotateMarker);
    // Set auto rotation of markers on chart
    Chart.AutoRotateMarker := True;
    // Save regular report
    (Report As IMetabaseObject).Save;
End Sub UserProc;

After executing the example auto rotation of markers in the graph direction is set on the regular report chart.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Public Shared Sub Main(Params: StartParams);

    Mb := Params.Metabase;
    Report := MB.ItemById["REGULAR_REPORT"].Edit() As IPrxReport;
    // Get report chart

    Chart := Sheet.Objects.Item[0].Extension As IChart;
    Chart.Series.DefaultSerie.ResetInheritance(ChartSeriePropertyInheritance.cspiAutoRotateMarker);
    // Set auto rotation of markers on chart
