How to change the position of the axis in .NET MAUI Cartesian Charts?

The .NET MAUI Cartesian Chart has support for positioning the chart axis at its default position, opposite position, and anywhere in the chart area. You can achieve this by utilizing the CrossesAt property. This property specifies where the horizontal axis intersects or crosses the vertical axis, and vice versa.
Custom Position:
To position the chart axis anywhere in the chart area, set the specific value where the axis crosses the opposite axis to the CrossesAt property.
The following code snippet illustrates how to change the position of the axis to a custom position:

[XAML]

<chart:SfCartesianChart>
. . .
    <chart:SfCartesianChart.XAxes>
        <chart:NumericalAxis CrossesAt="130" />
    </chart:SfCartesianChart.XAxes>

    <chart:SfCartesianChart.YAxes>
        <chart:NumericalAxis CrossesAt="3" />
    </chart:SfCartesianChart.YAxes>
    
    <chart:LineSeries ItemsSource="{Binding Data}" 
                      XBindingPath="XValues"
                      YBindingPath="YValues"/>
    
</chart:SfCartesianChart>

[C#]

SfCartesianChart chart = new SfCartesianChart();
. . .
CategoryAxis primaryAxis = new CategoryAxis();
primaryAxis.CrossesAt = 130;
chart.XAxes.Add(primaryAxis);
NumericalAxis secondaryAxis = new NumericalAxis();
secondaryAxis.CrossesAt = 3;
chart.YAxes.Add(secondaryAxis);

LineSeries series = new LineSeries();
series.ItemsSource = (new ViewModel()).Data;
series.XBindingPath = "XValues";
series.YBindingPath = "YValues";
chart.Series.Add(series);

Output

Opposed position:
To position the chart axis in the opposite position, set the value as double.MaxValue to the CrossesAt property.
The following code snippet illustrates how to change the position of the axis to the opposite position

[XAML]

<chart:SfCartesianChart>
. . .
    <chart:SfCartesianChart.XAxes>
        <chart:CategoryAxis CrossesAt="{Static x:Double.MaxValue}"/>
    </chart:SfCartesianChart.XAxes>

    <chart:SfCartesianChart.YAxes>
        <chart:NumericalAxis CrossesAt="{Static x:Double.MaxValue}"/>
    </chart:SfCartesianChart.YAxes>
    
    <chart:LineSeries ItemsSource="{Binding Data}" 
                      XBindingPath="Name"
                      YBindingPath="Height"/>
    
</chart:SfCartesianChart>

[C#]

SfCartesianChart chart = new SfCartesianChart();
. . .
CategoryAxis primaryAxis = new CategoryAxis();
primaryAxis.CrossesAt = double.MaxValue;
chart.XAxes.Add(primaryAxis);
NumericalAxis secondaryAxis = new NumericalAxis();
secondaryAxis.CrossesAt = double.MaxValue;
chart.YAxes.Add(secondaryAxis);

LineSeries series = new LineSeries();
series.ItemsSource = (new ViewModel()).Data;
series.XBindingPath = "Name";
series.YBindingPath = "Height";
chart.Series.Add(series);
