IChartAbstractItem.Contains

Fore Syntax

Contains(Point: IGxPointF): Boolean;

Fore Syntax

Contains(Point: IGxPointF): boolean;

Parameters

Point.

Description

The Contains property checks whether the point is included into the object.

Comments

This property returns True if the object contains this point, otherwise the property returns False.

Fore Example

This example assumes that there is the Chart object of the IChart type.

Add reference to Chart, Drawing, Ui system assemblies.

Sub UserProc;
Var
    Chart: IChart;
    Ser: IChartSerie;
    point: IGxPointF;
    b: Boolean;
Begin
    Ser := Chart.Series.Item(0);
    point := New GxPointF.Create(1, 1);
    b := Ser.Contains(point);
    If b Then WinApplication.InformationBox("The point is included into the sereis");
        Else WinApplication.InformationBox("The point is not included into the series");
    End If;
End Sub UserProc;

After executing the example the system displays a message informing whether the point belongs to the series.

Fore.NET Example

Requirements and the result of execution of the Fore.NET example are similar to the Fore example.

Imports Prognoz.Platform.Interop.Chart;
Imports Prognoz.Platform.Interop.Drawing;
Imports Prognoz.Platform.Interop.Ui;
…
Public Shared Sub Main(Params: StartParams);
Var
    Chart: IChart;
    Ser: IChartSerie;
    point: GxPointF = New GxPointFClass();
    b: Boolean;
    WinAppCls: WinApplicationClass = New WinApplicationClassClass();
Begin
    Ser := Chart.Series.Item[0];
    b := Ser.Contains(point);
    If b Then WinAppCls.InformationBox("The point is included into the series", Null);
        Else WinAppCls.InformationBox("The point is not included into the series", Null);
    End If;
End Sub;
