IChartSerie.Background

Syntax

Background: IChartBackgroundInfo;

Description

The Background property determines fill options for a data series.

Comments

Fill type is determined by the Type property. For each fill type there is a corresponding set of properties of the IChartBackgroundInfo interface.

Fill type application is limited by chart types described in the ChartBackgroundType enumeration.

Fore Example

Executing the example requires a histogram in regular report with the REGULAR_REPORT identifier. Add links to the Chart, Drawing, Metabase, Report, Tab system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Report: IPrxReport;
    Sheet: ITabSheet;
    Chart: IChart;
    Serie: IChartSerie;
Begin
    MB := MetabaseClass.Active;
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    Sheet := (Report.Sheets.Item(0) As IPrxTable).TabSheet;
    Chart := Sheet.Objects.Item(0).Extension As IChart;
    Serie := Chart.Series.Item(0);
    Serie.Background.Type := ChartBackgroundType.Gradient;
    Serie.Background.Color := GxColor.FromName("Red");
    Serie.Background.GradientColor := GxColor.FromName("Yellow");
    (Report As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the chart series is filled with red and yellow gradient.

Fore.NET Example

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

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

Public Shared Sub Main(Params: StartParams);
Var
    MB: IMetabase;
    Report: IPrxReport;
    Sheet: ITabSheet;
    Chart: IChart;
    Serie: IChartSerie;
    GxColorCls: GxColorClassClass = New GxColorClassClass();
Begin
    MB := Params.Metabase;
    Report := MB.ItemById["REGULAR_REPORT"].Edit() As IPrxReport;
    Sheet := (Report.Sheets.Item[0] As IPrxTable).TabSheet;
    Chart := Sheet.Objects.Item[0].Extension As IChart;
    Serie := Chart.Series.Item[0];
    Serie.Background.Type := ChartBackgroundType.cbtGradient;
    Serie.Background.Color := GxColorCls.FromName("Red");       
    Serie.Background.GradientColor := GxColorCls.FromName("Yellow");
    (Report As IMetabaseObject).Save();
End Sub;
