IChartAxis.AllowOverlapLabels

Fore Syntax

AllowOverlapLabels: Boolean;

Fore.NET Syntax

AllowOverlapLabels: Boolean;

Description

The AllowOverlapLabels property determines whether chart labels are overlapped.

Comments

The property is outdated, use IChart.TickLabelSpacingAuto.

The property is set to False by default, and labels are not overlapped.

If the property is set to True and:

If IChartAxis.TextIsMultiline is set to True, labels are overlapped only if the label text cannot be wrapped to a new line.
If IChartAxis.TextIsMultiline is set to False, the labels are overlapped instead of cutting with dots.

In the interface the property is set using the Allow Overlap Labels checkbox on the View tab of the Axis Format dialog box.

Fore Example

To execute the example, add a link to the MathFin system assembly . Place the Button, UiChart and ChartBox components on the form. Specify UiChart as the source of ChartBox. Specify points and series number for UiChart.

Class TestForm: Form
    Button1: Button;
    ChartBox1: ChartBox;
    UiChart1: UiChart;

    Sub UiChart1OnGetDataValue(Sender: Object; Args: IUiChartGetDataValueEventArgs);
    Begin
        Args.Result := True;
        Args.Value := Math.RandBetween(10,40);
    End Sub UiChart1OnGetDataValue;

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
        Var
        chart: IChart;
    Begin
        chart := UiChart1.Chart;
        chart.AxisX.AllowOverlapLabels := True;
    End Sub Button1OnClick;

End Class TestForm;

Click the button on the form. After executing the example labels of the X axis are overlapped.

Fore.NET Example

To execute the example, add a link to the Chart system assembly. Place the Button, uiChartNet and chartBoxNet components on the form. Specify uiChartNet as the source of chartBoxNet.

Imports Prognoz.Platform.Interop.Chart;
...
    Private Sub OBJ1656Form_Shown(sender: System.Object; e: System.EventArgs);
    Begin
        uiChartNet1.PointCount := 5;
        uiChartNet1.SerieCount := 2;
    End Sub;

    Private Sub button1_Click(sender: System.Object; e: System.EventArgs);
    Var
        chart: DxChart;
    Begin
        chart := uiChartNet1.ChartUi.Chart;
        chart.AxisX.AllowOverlapLabels := True;
    End Sub;
End Class;

Click the button on the form. After executing the example labels of the X axis are overlapped.
