Can't display OxiPlot pie series in Avalonia project

[LyubomiRadev]

I am trying to display a pie graphic using the oxiplot tool, but I am not able to display the graphic. As seen in MainView.axaml I am trying to display the PieSeries chart using ItemsSource by binding a collection. However the chart is not displayed. Am I doing something wrong or is this a bug? The code can be found here. I am also not able to display the percentage numbers seen in the second pie chart in the attached picture. It seems that when the data is dynamic the percentage info is not displayed.
