I have a RadPieChart in my application. When removing the app from the backstack and service is running, then opening the app from the notification, the app crashes with: 

Java.Lang.IllegalStateException: ChildNode is already parented by a ChartElement instance.

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

An exception is thrown when setting the ChartPallete FillColor property. The issue is reproduced on all platforms.

Workaround:

Also set the StrokeColor property.

<telerik:ChartPalette>
    <telerik:ChartPalette.Entries>
        <telerik:PaletteEntry FillColor="Red" StrokeColor ="Yellow"/>
        <telerik:PaletteEntry FillColor="Gray" StrokeColor ="Yellow" />
        <telerik:PaletteEntry FillColor="Blue" StrokeColor ="Yellow"/>
    </telerik:ChartPalette.Entries>
</telerik:ChartPalette>

Hi team,

Currently, I can only set LegendItemFontColor and LegendItemFontSize. I would like to be able to set LegendItemFontFamily

Thank you,

John

Hi Team,

I would like to be able to set different cap styles on the bars, like the RadGauge allows you to do on Indicators. For example, I want rounded corners.

Thank you,

John

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
    }
}

I would like to use line style instead of colour to distinguish between the different series on my chart as below. 

Is this possible?

From the docs it looks like we can only customise stroke colour and thickness. 

Thanks =)

Can the Legend be identical to the LineSeries, not only by colour, but also by style?

Can I customize the text inside the bar?

- Text Color, Position, FontSize, etc.

I just made a little test application using the .NET 6 Preview 6 and MAUI with chart control to see if we can use it for a future project. I was able to display just a basic chart with 1000 points in it, in ascending order on X axis. But the performance is really not there when running on my Android 10 device. I only made a Zoom at factor 2 and use panning right to left and it's not smooth at all. There is nothing in the chart (no grid, no annotations). Just a simple 2 axis chart. I can really not go with this because there will be many more data in our product at the chart need to be fast enough. Maybe it's a settings somewhere that need to be adjusted... Take a note that I was able to run the chart in WinUI project and the performance is correct, but I am on a very fast PC, it is just normal to be fast. Note: There is some kind of deceleration effect when panning, I want to disable it but not found how.

Anyway, it will be really cool if you can provide a very simple MAUI test application with the fastest full screen chart with Pan/Zoom with 1000 points (which for me is really not much data) and the corresponding code to me to validate if your library can do the job. I know that MAUI and .NET 6 is not released yet, but performance should be there now because it's really close to bug fixing only state now. Thanks.
