An API for tooltip position inside the trackball behavior will be a good addition to the Trackball behavior, as in this way you can manage the tooltip position. for example left, right, center, stretch, etc,

when trying to display data using the trackball, the tooltip is clipped on left at chart start: 

when having a chart with horizontal datetime axis and trackball behavior, the first and last points are not displayed in the trackball

when using categorical axis, the last point displays in the tooltip, but the first point does not.

Currently to achieve this I have to access the native chart and apply a gradient on the native chart series fill and stroke on iOS/Mac 

on WinUI I have to define a new template for the series PointTemplate. and set the color.

 

When having a tap gesture with single tap added to the chart control, the tap event is raised on double tap. 

Last label on the x axis is clipped, when the y axis is right positioned and x axis plot mode is on ticks.

i want to set a value for spacing between the legend icon with the color and the text

when rendering thousands of data, provide fast line chart. This type of series can be used for system performance monitoring or with chart than need to display thousands data points.

WinForms has fast line chart: https://docs.telerik.com/devtools/winforms/controls/chartview/series-types/fastline 

NullReferenceException when Chart is added inside Microsoft MAUI CollectionView and navigating back to a page.

Workaround:

When using the Telerik MAUI CollectionView no exception.

In WPF ChartView there is a TickOrigin property, provide such in MAUI Chart control.

Provide a way to invert the axis range in a similar way as in WPF ChartView: https://docs.telerik.com/devtools/wpf/controls/radchartview/axes/inversed-axis

Putting the Path or MultiPath inside of a ScrollView with a VerticalStack leads to an exception.

I would like to enumerate the legend into a table with 2 columns as in WPF Legend: https://docs.telerik.com/devtools/wpf/controls/radlegend/itemspanel

In Telerik WPF Chart there is an option to select a data point from a series https://docs.telerik.com/devtools/wpf/controls/radchartview/features/behaviors/selection#programmatic-selection Provide such option for the Telerik MAUI Chart.

Provide a way to invoke the tooltip for a concrete data point programmatically

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

The data points should allow setting shape and color to each one individually.

If the Chart control is nested inside a ScrollView, it is not sized properly on Android - it seems it occupies the available space, but the chart itself ( the axes and the series) are shrunk in size.

If you access the native chart control and made some customization on handler changed, the customizations are reset when series are updated. 

LineSeries Stroke and StrokeThickness are not applied when Palette is set
