IChartAxisLevelLines.Add

Syntax

Add(Value: Double; [Pen: IGxPen = Null]): Integer;

Parameters

Value. Value of added level.

Pen. Optional parameter that determines parameters of the added level line. The default value is Null.

Description

The Add method adds a new level line to the chart and returns the index of this level.

Example

Executing the example requires a regular report with the REGULAR_REPORT identifier, which sheet contains a chart with the source data and at least three level lines. Add links to the Metabase, Report, Tab, Chart, Drawing system assemblies in the unit.

Sub UserProc;
Var
    MB: IMetabase;
    Report: IPrxReport;
    Tab: ITabSheet;
    Chart: IChart;
    LevelLine: IChartAxisLevelLine;
    Pen: IGxPen;
Begin
    MB := MetabaseClass.Active;
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    Tab := (Report.Sheets.Item(0) As IPrxTable).TabSheet;
    Chart := Tab.Objects.Item(0).Extension As IChart;
    Chart.AxisY.LevelLines.Remove(0);
    Pen := New GxPen.CreateSolid(GxColor.FromKnownColor(GxKnownColor.Blue), 0.40);
    Chart.AxisY.LevelLines.Add(12.2, Pen);
    LevelLine := Chart.AxisY.LevelLines.Item(1);
    LevelLine.Value := 15.4;
    (Report As IMetabaseObject).Save;
End Sub UserProc;

The level lines are changed on the regular report chart: the first line is removed, the third line's value is changed, a line with the specified thickness and color is added.
