I need to add more values ​​dynamically, how do I do this?

Answer 1

Node data (source: GoJS docs, class Model ):

If you want to add or remove node data from nodeDataArray, call addNodeData or removeNodeData .

Bind data (source: GoJS docs, GraphLinksModel class ):

If you want to add or remove link data from linkDataArray, call addLinkData or removeLinkData . If you want to change the node link that the link refers to, call setFromKeyForLinkData and / or setToKeyForLinkData .
