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(new[]
{
new BarItem{ Value = Registrar.OrderBy(c => c.Especie).Select(x => x.Ancho),
},

             }),
            LabelPlacement = LabelPlacement.Inside,
            LabelFormatString = "{0}"
        };
