I have a LineSeries with data values on the Y-axis and DateTime on the X-axis.
Sometimes the data values are < 0 and our end user requirement is to show a graph with X-axis crossing at Y=0.
I tried to add this in my View.xaml according to the SyncFusion documentation (https://help.syncfusion.com/xamarin/sfchart/axis) - "Axis can be positioned anywhere in the chart area by using CrossesAt property."

<chart:DateTimeAxis CrossesAt="0">

But this particular property fails to be recognized by mono runtime and thus crashes the app.

Unhandled Exception:

You can resolve your issue by modifying DateTimeHelper.CS. Please refer below code snippet:

Code snippet [XAML]:

 <chart:SfChart.SecondaryAxis>
 <chart:NumericalAxis CrossesAt="x:Static local:DateTimeHelper.Date" >
 </chart:NumericalAxis>

Code snippet [C#]:

public static class DateTimeHelper

 public static DateTime Date
 
 get return new DateTime(2018, 11, 03); 
 

Or else you can set CrossesAt value in C#.

Code snippet [C#]:

Chart.SecondaryAxis.CrossesAt = new DateTime(2018, 11, 03);

And have prepared a sample based on your requirement and you can download the sample from the below link:
