Gantt Chart functionality in LiveCharts2 for Uno

[butti71]

Is your feature request related to a problem? Please describe.
In an old version of LiveCharts you added the Gantt Chart functionality (Issue #351) which I found very promising! I tried to access that functionality in an Uno App with livechart2, but it is not available any more.

Describe the solution you'd like
Gantt chart functionality as described here: (Issue #351)

Describe alternatives you've considered
Using the SkiaSharp library to create my own Gantt view.

I did find a solution: Use StackedRowSeries.

1. You would create a mapper for your task class like so :LiveCharts.Configure(config => config.HasMap<Task>((Taks, point) => new(Task.ID, Task.Duration)));
2. Then, in your ViewModel, for each of your task :

• you would create first another decoy task that starts at 0 and lasts until the start of the task you want to draw. On each of the decoy taks, assign a specific field, such as bool VoidForGraph = true;
• add them both to a serie like so:
  Series.Add(new StackedRowSeries<Task> {values = [decoyTask,Task], DataLabelsFormatter = (point) => (point.Model?.VoidForGraph ? "" : $"{(point.Model?.Name is null ? "" : point.Model.Name)}starts {point.Model.Start:N2} ends {point.Model.End:N2} }
• use a conditionnal formated so that the decoyTask is not visible, such as
  .OnPointMeasured(point => { if (point.Visual is null) return; point.Visual.Stroke = point.Model?.Status == JobStatus.VoidForGraph ? Null : new SolidColorPaint(SKColors.Blue); })

3. Fine tune as you want with DataLabelFormaters, colors, other broken tasks etc...
