XAxes disappear when using mapping of DateTime

[cris-m]

XAxes disappear when using mapping of DateTime. I have the following data:

public class Transaction
{
    public string TransactionId { get; set; }
    public string ReferenceNumber { get; set; }
    public string RecipientId { get; set; }
    public string RecipientName { get; set; }
    public string Country { get; set; }
    public string CurrencyCode { get; set; }
    public string PaymentMethod { get; set; }
    public double Amount { get; set; }
    public double TransactionFee { get; set; }
    public TransactionStatus Status { get; set; }
    public TransactionType TransactionType { get; set; }
    public DateTime DateTime { get; set; }
}

public ObservableCollection<Transaction> Transactions = new ObservableCollection<Transaction>
    {
        new Transaction
        {
            TransactionId = Guid.NewGuid().ToString(),
            ReferenceNumber = "REF2103210930423",
            RecipientId = "123",
            RecipientName = "Alice",
            Country = "DRC",
            CurrencyCode = "USD",
            PaymentMethod = "Credit Card",
            Amount = 100.0,
            TransactionFee = 2.0,
            Status = TransactionStatus.Completed,
            TransactionType = TransactionType.Deposit,
            DateTime = DateTime.Now.AddDays(-2)
        },
        new Transaction
        {
            TransactionId = Guid.NewGuid().ToString(),
            ReferenceNumber = "REF2103210930123",
            RecipientId = "456",
            RecipientName = "Bob",
            Country = "US",
            CurrencyCode = "USD",
            PaymentMethod = "Mobile Money",
            Amount = 340.0,
            TransactionFee = 1.0,
            Status = TransactionStatus.Completed,
            TransactionType = TransactionType.Withdrawal,
            DateTime = DateTime.Now.AddDays(2)
        }
  }

I create a list of series and axis

public List<ISeries> Series { get; set; } = new List<ISeries>();
public List<Axis> XAxes { get; set; } = new List<Axis>();
 public List<Axis> YAxes { get; set; } = new List<Axis>();

Series.Add(new LineSeries<Transaction>
{
    Name = "Received",
    DataLabelsSize = 4,
    LineSmoothness = 2,
    GeometryStroke = new SolidColorPaint(Themes.Current.Primary.ToSKColor(), 2.0f),
    GeometryFill = new SolidColorPaint(Themes.Current.Background.ToSKColor()),
    GeometrySize = 10,
    Fill = new LiveChartsCore.SkiaSharpView.Painting.LinearGradientPaint(
        new[] {

            Themes.Current.Primary.ToSKColor(150),
            Colors.Transparent.ToSKColor(),
         },
        new SKPoint(0.5f, 0),
        new SKPoint(0.5f, 1)
    )
    { StrokeThickness = 10 },
    Stroke = new SolidColorPaint(Themes.Current.Primary.ToSKColor()) { StrokeThickness = 2 },
    Values = new ObservableCollection<Transaction>(transations),
    Mapping = (x, point) => new Coordinate(x.DateTime.Ticks, x.Amount)
};

Axes.Add(
new Axis
{
    TextSize = 10,
    Labels = transations.Select(t => t.DateTime.ToString("MMMM dd")).ToArray(),
    Padding = new LiveChartsCore.Drawing.Padding(4),
    LabelsRotation = 45,
    LabelsPaint = new SolidColorPaint(Themes.Current.OnBackground.ToSKColor()),
    SeparatorsAtCenter = false,
    DrawTicksPath = true
};

Axes.Add(
new Axis
{
    IsVisible = false
};

Now using on CartesianChart chart

new CartesianChart()
    .Series(Series)
    .HeightRequest(200)
    .TooltipPosition(TooltipPosition.Top)
    .AnimationsSpeed(new TimeSpan(0, 0, 0, 0, 500))
    .EasingFunction((time) => time * time)
    .DrawMargin(new Margin(5))
    .XAxes(XAxes)
    .YAxes(YAxes)

Here is the result

• Padding is added on the bottom of she chart
• Chart height is not correct.
• XAxes is invisible.

Using the following like in documentation I get an error:

Mapping = (transaction, point) => {
      point.Coordinate = new Coordinate(transaction.DateTime, transaction.Amount)
  }

Not all code paths return a value in lambda expression of type 'Func<Transaction, int, Coordinate>'
