    Gauge Axis Anchors
    In This Topic

    Gauge axis anchor control the position and orientation of gauge axes in gauge model space. There are two types of gauge axis anchors:

    Type Description
    NDockGaugeAxisAnchor  Docks the axis to the top or bottom of the gauge model space.
    NModelGaugeAxisAnchor Positions the axis on a specified value in the gauge model space.

    Note: Both anchor types have a BeginPercent and EndPercent properties that allow you to define the start and end point along the X axis in gauge model coordinates. This allows you to have axes that cover a different range as shown by the code snippet below.
     Docking Gauge Axes

    The following code will create a new gauge axis docked at the top of the of the gauge:

    C#
    Copy Code
    nChartControl1.Panels.Clear();
    NRadialGaugePanel radialGauge = new NRadialGaugePanel();
    NGaugeAxis axis = new NGaugeAxis();
    axis.Anchor = new NDockGaugeAxisAnchor(GaugeAxisDockZone.Top, true, 50, 100);
    axis.Range = new NRange1DD(50, 100);
    radialGauge.Axes.Add(axis);
    radialGauge.SweepAngle = 270; 
    nChartControl1.Panels.Add(radialGauge);
    
    Visual Basic
    Copy Code
    NChartControl1.Panels.Clear()
    Dim radialGauge As New NRadialGaugePanel
    Dim axis As New NGaugeAxis 
    axis.Anchor = New NDockGaugeAxisAnchor(GaugeAxisDockZone.Top, True, 50, 100)
    axis.Range = New NRange1DD(50, 100)
    radialGauge.Axes.Add(axis)
    radialGauge.SweepAngle = 270 
    NChartControl1.Panels.Add(radialGauge)
    

    The above code will result in the following gauge axis configuration:


     Model Gauge Axis Anchors

    Alternatively you can position gauge axes at specified model coordinates. The following code will add a secondary axis to the gauge that is positioned at the gauge center in model space:

    C#
    Copy Code
    nChartControl1.Panels.Clear();
    NRadialGaugePanel radialGauge = new NRadialGaugePanel();
    NGaugeAxis axis = new NGaugeAxis();
    axis.Anchor = new NModelGaugeAxisAnchor(new NLength(0), VertAlign.Center, RulerOrientation.Left, 0, 100);
    radialGauge.Axes.Add(axis);
    radialGauge.SweepAngle = 270; 
    NChartControl1.Panels.Add(radialGauge);
    
    Visual Basic
    Copy Code
    NChartControl1.Panels.Clear()
    Dim radialGauge As New NRadialGaugePanel 
    Dim axis As New NGaugeAxis
    axis.Anchor = New NModelGaugeAxisAnchor(New NLength(0), VertAlign.Center, RulerOrientation.Left, 0, 100)
    radialGauge.Axes.Add(axis)
    radialGauge.SweepAngle = 270 
    NChartControl1.Panels.Add(radialGauge)
    

    This is how the gauge axes will look after the above code is executed:
