I am using concept map to make one of my diagram.
Problem - this is always rearranging it self on page reload. How can I save its state (x and y positions, and zoom levels) ? so that I can reopen this diagram and it will open me the same I was working before
Declare a Binding of Node.location to some new “location” property on your node data object. Make it a TwoWay Binding if you want save any changes that might happen while editing. Lots of samples and many examples in the Introduction do this.
Once you have locations stored for each node, you will not need to set the Diagram.layout.
