            // Now the Y axis we will display it as currency

            // 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
