The entire content of the schematic diagram is updated according to the updated trace result based on the trace parameters that were persisted in the schematic database when the diagram was generated. As the switch has been closed, the trace goes beyond the switch. Without selecting this new trace result in the map, Schematics has reexecuted the trace in memory and updated the diagram accordingly.

Remove the diagram data frame.

Note: If the trace downstream is reexecuted in the map starting from an edge flag placed at the same location it is when the diagram has is generated, updating diagram using the Current trace result will give the same result.

The Update Diagram dialog box also opens when right-clicking the schematic diagram entry in the TOC and clicking the Update Diagram shortcut menu.
