Hi Team,

If you create a ScatterPointSeries, the RadLegend does not pick up the series DisplayName value. A replication project is attached, but here's a screenshot to quickly illustrate the behavior:

Thank you,

when using the flowing setup: 

<telerik:RadCartesianChart.ChartBehaviors>
                    <telerik:ChartSelectionBehavior x:Name="selection"
                                                    SeriesSelectionMode="None"
                                                    DataPointSelectionMode="Single"
                                                SelectionChanged="selection_SelectionChanged"/>
</telerik:RadCartesianChart.ChartBehaviors>

the selection behavior on data point does not fire on WInUI on Cartesian series. It works for PieSeries. 

Labels in bar series are cut, when setting the labels VerticalAligment to Top:

On some chart series like, bar, line, scatter line, etc, the y axis line is hidden. make it visible, as it is on Android and Windows. 

Current solution is to use the chart handler changed and set YAxis.Style.LineHidden to false.

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();

        this.chart.HandlerChanged += this.Chart_HandlerChanged;
    }

    private void Chart_HandlerChanged(object sender, EventArgs e)
    {
        this.UpdateChart();
    }

    private void UpdateChart()
    {
        var platformView = this.chart.Handler.PlatformView;
#if IOS || MACCATALYST
        var platformChart = (Telerik.Maui.Controls.Compatibility.ChartRenderer.iOS.TKExtendedChart)platformView;
platformChart.YAxis.Style.LineHidden = false;
#endif
    }
}

When adding a plot band annotation to the date time axis, it is not applied on MacCatalyst and iOS. In addition if using binding, an exception is thrown.  

It works on Android and WinUI

Android.Views.WindowManagerBadTokenException: 'Unable to add window -- token null is not valid; is your activity running?'

Series labels are not properly rotated with LabelFitMode set to "Rotate".

On iOS it seems the issue happens only on simulator, on iPhone device the labels are aligned (rotated) as expected.

Legend is not fully visualized, the square color is missing, only the text is displayed.
on iOS it seems the issue happens only on simulator, on iPhone device SE 2022 the legend is  fully displayed

Improve performance when adding many series and data points are constantly added and increased
For example chart slows the performance when 4th series with many data points are added. 

For the test, I have used ScatterLine series.
