LTSpice noob question

[Michael Robinson]

I want to plot the transfer characteristic of a CMOS inverter, with input
voltage on the horizontal axis and output voltage on the vertical axis. If
I do a voltage sweep I guess I could get a graph that looks like the
transfer curve, but it will have units of time on the horizontal axis.
There must be some way to get a proper graph of output voltage versus input
voltage. How do you do that in LTSpice?

Left click on horizontal axis and change "time" to your input voltage.
