Call Graph View

The [Call Graph] view shows the function call information for the selected function in a report format.
(Ex: When calling function ‘B’ from function ‘A’, it is expressed ‘edge from node ‘A’ to node ‘B’, and it is represented as one edge even if called multiple times.
If you select the node (function), it shows the function call information for that node.
