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);

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)

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);

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)

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:
