Hi,

Windows Forms controls are rendered in their own windows, and the diagram control cannot draw over these windows. What you can do on your side is to draw these "custom plot" graphs inside DiagramNodes instead of using hosted controls. You have a few options:

- use a rectangular custom-drawn ShapeNode and handle the DrawNode event to plot the graph
- derive from DiagramNode and implement its Draw method
- create a graph Component and show the graphs inside CompositeNodes

In WpfDiagram hosted controls can freely mix with other elements in the diagram Z order since they are all part of the same WPF visual tree and are not rendered in separate windows.

I hope that helps,

If that component can export bitmap images or provides a public OnPaint(Graphics) method, you can still use it to draw inside nodes. E.g. you could keep its instance as a member of your custom node class, and then implement DiagramNode.Draw through that member. Btw. our chart/graph control can do that and also lets you plot using custom functions (see the sine function sample at http://mindfusion.eu/gallery-masterchart.html).

I hope that helps,
Stoyan
