IChartAxis.PositionValue

Syntax

PositionValue: Double;

Description

The PositionValue property determines an absolute distance to intersection with the orthogonal axis.

Comments

To set the distance, set the IChartAxis.Position property to ChartAxisPosition.Custom.

Example

To execute the example, create a form and place the ChartBox, UiChart, Button and FloatEdit components with the default identifiers on the form. The UiChart1 component is a source for the ChartBox1 component. Specify a link to the MathFin system assembly in the inspector of assemblies.

The UiChart1OnGetDataValue procedure is a handler of the OnGetDataValue event for the UiChart1 component.

The MyFormOnShow procedure is a handler of the OnShow event for the form.

The Button1OnClick procedure is a handler of the OnClick event for the button.

Sub UiChart1OnGetDataValue(Sender: Object; Args: IUiChartGetDataValueEventArgs);
Begin
    Args.Result := True;
    Args.Value := Math.Rand;
End Sub UiChart1OnGetDataValue;

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Chart: IChart;
    X : IChartAxis;
Begin
    Chart := ChartBox1.Chart;
    X := Chart.AxisX;
    X.Position := ChartAxisPosition.Custom;
    X.PositionValue := FloatEdit1.Value;
End Sub Button1OnClick;

Sub MyFormOnShow(Sender: Object; Args: IEventArgs);
Begin
    UiChart1.PointCount := 3;
    UiChart1.SerieCount := 4;
End Sub OBJ37234FormOnShow;

Set the distance till intersecting with the orthogonal axis and click the button. Position of the X axis will be changed.
