Two Diagrams for different views of the same data (Read 3362 times)

	I have a new requirement to display my data in two slightly different ways. View A - Nodes can have multiple links in the same direction, all with labels (i.e. Node X can have 3 links to Node Y, and Node Y can have 2 links to Node X, all with different labels) View B - Same Nodes as View A, but only allow single link in each direction, different labels on the links (i.e. Node X can have 1 link to Node Y and Node Y can have one link to Node X). The 'single link' in this view is a sum of the (possibly) multiple links in view A. I'm thinking that the best way to do this is to have two different Diagrams, one for each View. The problems come from the fact that the user must be able to switch views. And edit the diagram in either view, and changes such as added/removed/changed Nodes and links must be reflected in the other view. Do you think that having 2 diagrams is the right way to go about this? Have you any comments on how easy it would be to replicate changes on one View within the other if they are separate Diagrams?

	If nodes' positions would not change between views, try implementing this using layers. Set link.LayerIndex to either 0 or 1 for the different kinds of links, and add two Layer objects to the diagram.getLayers() collections. Keep the Layer.Visible property for one of the layers set to false, and when switching between views toggle its value for both layers. If you need to keep both views visible at same time, you might have to derive from the Layer class and override its getVisible method to determine whether it should be visible dynamically depending on the view. I hope that helps, Stoyan

	The layers method you outlined is looking really good and will be much easier to maintain Thank you for your help.
