When doing nonlinear circuit design, you can setup nonlinear measurements to measure at a probe. The probe can be moved after simulation to show values at that probe without requiring a new simulation.
For example, see this simple schematic and the graph measuring the voltage waveform at the M_PROBE with the ID of VP1.
Then moving the probe in the schematic by clicking and dragging to a new node will update the waveform for the voltage at new node location.
Finally, if the probe is on the ground, we would expect no voltage.
Watch a video that demonstrates this in more detail and a bonus feature of a dynamic probing mode.
