Axis Labels
This sample uses C# 12 features, it also uses features from the CommunityToolkit.Mvvm package, you can learn more about it here.
This web site wraps every sample using a UserControl instance, but LiveCharts controls can be used inside any container.

FontFamily = "Times New Roman",
SKFontStyle = new SKFontStyle(
SKFontStyleWeight.ExtraBold,
SKFontStyleWidth.Normal,
SKFontStyleSlant.Italic)
},
// Use the Labeler property to give format to the axis values // mark
// Now the Y axis labels have a currency format.
// LiveCharts provides some common formatters
// in this case we are using the currency formatter.
Labeler = Labelers.Currency // mark
// you could also build your own currency formatter
// for example:
// Labeler = (value) => value.ToString("C")
// but the one that LiveCharts provides creates shorter labels when
// the amount is in millions or trillions
