Getting Started

This section explains the steps required to configure a SfLinearGauge control in a real-time scenario and also provides a walk-through on some of the customization features available in SfLinearGauge control.

Adding gauge references

Refer to this article to know how to add Syncfusion controls to Visual Studio projects in various ways. You can also refer to this link to know about the assemblies required for adding gauge to your project.

Initialize gauge

Import the SfLinearGauge namespace to your respective Window as follows.

xmlns:gauge="using:Syncfusion.UI.Xaml.Gauges"
using Syncfusion.UI.Xaml.Gauges;

You can initialize an empty SfLinearGauge control.

<gauge:SfLinearGauge/>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

this.Content = sfLinearGauge;

Adding header

You can assign a unique header to SfLinearGauge by using the Header property and position it wherever as you desired by using the HeaderOffset property.

<gauge:SfLinearGauge Header="Thermometer"  HeaderFontSize="15" HeaderOffset="0.47,0.38">

      </gauge:SfLinearGauge>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

            sfLinearGauge.Header = "Thermometer";

            sfLinearGauge.HeaderFontSize = 15;

            sfLinearGauge.HeaderOffset = new Point(0.47, 0.38);

            this.Content = sfLinearGauge;

Configuring scale

Configuring scale

You can configure the LinearScale elements by making use of following API’s available in SfLinearGauge.
They are:

• ScaleDirection

• ScaleBarStroke

• ScaleBarSize

• ScaleBarLength

• ScaleBarBorderThickness

• Interval

• Minimum

• Maximum

<gauge:SfLinearGauge>

    <gauge:SfLinearGauge.MainScale>

    <gauge:LinearScale     Interval="10" 

     MajorTickStroke="Gray" MajorTickSize="25"    MinorTickSize="12" LabelSize="15"

     MinorTickStroke="Gray" LabelStroke="#424242"  MinorTicksPerInterval="3" ScaleBarLength="300">

    </gauge:LinearScale>

    </gauge:SfLinearGauge.MainScale>

    </gauge:SfLinearGauge>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

            LinearScale linearScale = new LinearScale();

            linearScale.Interval = 10;

            linearScale.LabelSize = 15;

            linearScale.MajorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.MinorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.LabelStroke = new SolidColorBrush(Color.FromArgb(0xff, 0x42, 0x42, 0x42));

            linearScale.MajorTickSize = 25;

            linearScale.MinorTickSize = 12;

            linearScale.ScaleBarLength = 300;

            linearScale.MinorTicksPerInterval = 3;

            sfLinearGauge.MainScale = linearScale;

Adding ranges

You can categorize the scale values using the start and end values properties in LinearRange. You can add multiple ranges for a scale using the Ranges property.

<gauge:SfLinearGauge>

            <gauge:SfLinearGauge.MainScale>

            <gauge:LinearScale     Interval="10" 
                                   MajorTickStroke="Gray" MajorTickSize="25" 
                                   MinorTickSize="12" LabelSize="15" ScaleBarSize="10"
                                   MinorTickStroke="Gray" LabelStroke="#424242"
                                   MinorTicksPerInterval="3" ScaleBarLength="300">

                <gauge:LinearScale.Ranges>
                    
                    <gauge:LinearRange     StartValue="0" EndValue="40"
                                           RangeStroke="#27BEB7"  StartWidth="10"
                                           EndWidth="10" RangeOffset="0.4" />
                    
                    <gauge:LinearRange     StartValue="40" EndValue="100"
                                           RangeStroke="LightCyan" RangeOffset="0.4"
                                           StartWidth="10"  EndWidth="10"/>
                    
                </gauge:LinearScale.Ranges>


            </gauge:LinearScale>

            </gauge:SfLinearGauge.MainScale>

        </gauge:SfLinearGauge>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

            LinearScale linearScale = new LinearScale();

            linearScale.Interval = 10;

            linearScale.LabelSize = 15;

            linearScale.ScaleBarSize = 10;

            linearScale.MajorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.MinorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.LabelStroke = new SolidColorBrush(Color.FromArgb(0xff, 0x42, 0x42, 0x42));

            linearScale.MajorTickSize = 25;

            linearScale.MinorTickSize = 12;

            linearScale.ScaleBarLength = 300;

            linearScale.MinorTicksPerInterval = 3;

            LinearRange linearRange = new LinearRange();

            linearRange.StartValue = 0;

            linearRange.EndValue = 40;

            linearRange.RangeStroke = new SolidColorBrush(Color.FromArgb(0xff,0x27,0xBE,0xB7));

            linearRange.StartWidth = 10;

            linearRange.EndWidth = 10;

            linearRange.RangeOffset = 0.4;

            linearScale.Ranges.Add(linearRange);

            LinearRange linearRange1 = new LinearRange();

            linearRange1.StartValue = 40;

            linearRange1.EndValue = 100;

            linearRange1.RangeStroke = new SolidColorBrush(Colors.LightCyan);

            linearRange1.RangeOffset = 0.4;

            linearRange1.StartWidth = 10;

            linearRange1.EndWidth = 10;

            linearScale.Ranges.Add(linearRange1);

            sfLinearGauge.MainScale = linearScale;

Adding a symbol pointer

SymbolPointer is a shape that can be placed to mark the pointer value in gauge.

<gauge:SfLinearGauge>

            <gauge:SfLinearGauge.MainScale>

            <gauge:LinearScale     Interval="10" 
                                   MajorTickStroke="Gray" MajorTickSize="25" 
                                   MinorTickSize="12" LabelSize="15" ScaleBarSize="10"
                                   MinorTickStroke="Gray" LabelStroke="#424242"
                                   MinorTicksPerInterval="3" ScaleBarLength="300">

                <gauge:LinearScale.Pointers>

                    <gauge:LinearPointer    PointerType="SymbolPointer" Value="60"
                                            SymbolPointerHeight="10" SymbolPointerWidth="10"
                                            SymbolPointerPosition="Below" SymbolPointerStroke="#757575"/>

                </gauge:LinearScale.Pointers>

            </gauge:LinearScale>

            </gauge:SfLinearGauge.MainScale>

        </gauge:SfLinearGauge>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

            LinearScale linearScale = new LinearScale();

            linearScale.Interval = 10;

            linearScale.LabelSize = 15;

            linearScale.ScaleBarSize = 10;

            linearScale.MajorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.MinorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.LabelStroke = new SolidColorBrush(Color.FromArgb(0xff, 0x42, 0x42, 0x42));

            linearScale.MajorTickSize = 25;

            linearScale.MinorTickSize = 12;

            linearScale.ScaleBarLength = 300;

            linearScale.MinorTicksPerInterval = 3;

            LinearPointer linearPointer = new LinearPointer();

            linearPointer.PointerType = LinearPointerType.SymbolPointer;

            linearPointer.Value = 60;

            linearPointer.SymbolPointerHeight = 10;

            linearPointer.SymbolPointerWidth = 10;

            linearPointer.SymbolPointerPosition = LinearSymbolPointersPosition.Below;

            linearPointer.SymbolPointerStroke = new SolidColorBrush(Color.FromArgb(0xff,0x75,0x75,0x75));

            linearScale.Pointers.Add(linearPointer);

            sfLinearGauge.MainScale = linearScale;

Adding a bar pointer

BarPointer is used to mark the scale values. This starts at the beginning of gauge and ends at the pointer value.

<gauge:SfLinearGauge>

            <gauge:SfLinearGauge.MainScale>

            <gauge:LinearScale     Interval="10"

                                   MinorTickStroke="Gray" LabelStroke="#424242"
                                   MinorTicksPerInterval="3" ScaleBarLength="300">

                    <gauge:LinearPointer PointerType="BarPointer" Value="50" BarPointerStroke="#757575"
                                             BarPointerStrokeThickness="10"/>

                </gauge:LinearScale.Pointers>

            </gauge:LinearScale>

            </gauge:SfLinearGauge.MainScale>

        </gauge:SfLinearGauge>
SfLinearGauge sfLinearGauge = new SfLinearGauge();

            LinearScale linearScale = new LinearScale();

            linearScale.Interval = 10;

            linearScale.LabelSize = 15;

            linearScale.ScaleBarSize = 10;

            linearScale.MajorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.MinorTickStroke = new SolidColorBrush(Colors.Gray);

            linearScale.LabelStroke = new SolidColorBrush(Color.FromArgb(0xff, 0x42, 0x42, 0x42));

            linearScale.MajorTickSize = 25;

            linearScale.MinorTickSize = 12;

            linearScale.ScaleBarLength = 300;

            linearScale.MinorTicksPerInterval = 3;

            LinearPointer linearPointer1 = new LinearPointer();

            linearPointer1.PointerType = LinearPointerType.BarPointer;

            linearPointer1.Value = 50;

            linearPointer1.BarPointerStroke = new SolidColorBrush(Color.FromArgb(0xff, 0x75, 0x75, 0x75));

            linearPointer1.BarPointerStrokeThickness = 10;

            linearScale.Pointers.Add(linearPointer1);

            sfLinearGauge.MainScale = linearScale;
