Hi, I want to populate itemsource items with: var items = Registrar.OrderBy(c => c.Especie).Select(x => x.Ancho).ToList(); I was thinking of something like this perhaps?? var barSeries = new ColumnSeries { ItemsSource = new List<BarItem>(new[] { new BarItem{ Value = Registrar.OrderBy(c => c.Especie).Select(x => x.Ancho), }, }), LabelPlacement = LabelPlacement.Inside, LabelFormatString = "{0}" };
