  [DisplayName("Funnel"),
  CustomItemDescription("Funnel description"),
  CustomItemImage("CustomItemsSample.Images.Funnel.svg")]
  public class CustomFunnelMetadata : CustomItemMetadata{
     [DisplayName("Value"),
      EmptyDataItemPlaceholder("Value"),
      SupportColoring(DefaultColoringMode.Hue)]
      public Measure Value {
          get { return GetPropertyValue<Measure>(); }
          set { SetPropertyValue(value); }
      }
      [DisplayName("Arguments"),
      EmptyDataItemPlaceholder("Argument"),
      SupportColoring(DefaultColoringMode.Hue),
      SupportInteractivity]
      public DimensionCollection Arguments { get; } = new DimensionCollection();
  }
}
