Drag the cursor to the the maximum amplitude using LTspice

Click For Summary
SUMMARY

The discussion centers on finding the maximum power transfer in a circuit using LTspice. Users express the need for an automatic method to drag the cursor to the maximum or minimum amplitude of a signal during simulations. Currently, there is no built-in feature in LTspice for this functionality; users must manually drag the cursor and utilize zooming techniques to enhance visibility of the plot's critical points.

Homework Statement


So i am trying to find the maximum power transfer of a circuit. See attached image.
Is there any way to automatically drag the cursor of a plot to the maximum/minimum amplitude of a signal when simulating LTspice? Or do you need to manually drag the cursor and estimate values from the y-axis of the plot?

Hi DEU.Osterhagen.

I've made quite a lot of use of LTspice and haven't come across any automatic way to find the maximum of a plot. What I've been doing instead is using the ability to zoom in on sections of the plot to magnify the area of interest, making finding the maximum (or minimum) easier. Still need to drag the cursor though.
