publicvoid DisplayOpening()
{
T.Wpf.Controls.TLinearGaugeControl control =
this.CurrentDisplay.GetControl("TLinearGaugeControl1")as
T.Wpf.Controls.TLinearGaugeControl;
Syncfusion.UI.Xaml.Gauges.SfLinearGauge gauge = control.Content as
Syncfusion.UI.Xaml.Gauges.SfLinearGauge;
Syncfusion.UI.Xaml.Gauges.LinearRange range =new
Syncfusion.UI.Xaml.Gauges.LinearRange();
range.StartValue =300;
range.EndValue =500;
range.StartWidth =20;
range.EndWidth =30;
range.RangeStroke =new SolidColorBrush(Colors.Red);
gauge.MainScale.Ranges.Add(range);

Runtime Execution
The LinearGauge Control provides a visual representation of data ranges in a linear manner. Users can customize the gauge by setting its orientation, position, and the data it is linked to. The control allows for detailed adjustments including the start and end of the range, scale direction, interval, and size. Additionally, users can modify the appearance of labels, ticks, pointers, and range segments in terms of size, thickness, and stroke. This level of customization ensures that the LinearGauge Control can be tailored to fit the specific needs of any application that requires linear data display.
