Best way to extend the MapChart visualization

[Reidar Midtun]

I have implemented a factory like the following:

internal sealed class AttributeMapFactory : ConfiguredVisualFactory {

internal AttributeMapFactory() : base(

VisualTypeIdentifiers.MapChart2, // Type identifier for base visualization

AttributeMapPlotIdentifiers.Layer4DMapPlot,

// New Type identifier

VisualCategory.Visualization, // Visual category

Properties.Resources.layers, // Icon

null

) // License

}

 

Now I would like to extend my visual by adding som C# Forms controls to it (Labels and ToggleButtons). What is the best way to implement thisThe MapChart class is sealed and therefore cannot be extended. Is it possible to make aCustomVisualization that consists of standard Forms controls in addition to a Panel containing a MapChart or is there an alternative way of implementing it
