How to customize the Scale Values Based on your Business Logics in the .NET MAUI Linear Gauge?

The Syncfusion® .NET MAUI Linear Gauge (SfLinearGauge) allows you to customize scale values. This guide demonstrates how to customize the scale values based on your business logic.

XAML:
By utilizing the GenerateVisibleLabels, ValueToFactor, and FactorToValue callbacks, linear gauge enables you to show a series of values together with a custom scale based on your business logic.

<local:LinearGauge Minimum="1" Maximum="10000">
   <gauge:SfLinearGauge.MarkerPointers>
       <gauge:LinearShapePointer Value="1000" />
   </gauge:SfLinearGauge.MarkerPointers>
</local:LinearGauge>

C#:

public class LinearGauge : SfLinearGauge
{
   int labelsCount;
   public override List<GaugeLabelInfo> GenerateVisibleLabels()
   {
       List<GaugeLabelInfo> labelInfos = new List<GaugeLabelInfo>();
       int minimum = (int)LogBase(this.Minimum, 10);
       int maximum = (int)LogBase(this.Maximum, 10);
       for (int i = minimum; i <= maximum; i++)
       {
           double value = Math.Floor(Math.Pow(10, i));
           GaugeLabelInfo label = new GaugeLabelInfo()
           {
               Value = value,
               Text = value.ToString()
           };
           labelInfos.Add(label);
       }

       labelsCount = labelInfos.Count;
       return labelInfos;
   }

   private double LogBase(double value, int baseValue)
   {
       return Math.Log(value) / Math.Log(baseValue);
   }

   public override double ValueToFactor(double value)
   {
       return LogBase(value, 10) / (labelsCount - 1);
   }

   public override double FactorToValue(double factor)
   {
       return Math.Pow(Math.E, factor * (labelsCount - 1) * Math.Log(10));
   }
}
