LTSpice: plot frequency v. power?

[Paul Burridge]

Hi,

Possibly a dumb question, what's the best way to do this? I need a
plot of frequency of a voltage source v. power supplied into a load
via an impedance matching network.
Normally I'd fiddle about until I found a way of doing this but my
main computer's up the creek. Anyone know for sure?

You can probably do it with a user-defined function.

Plot V*I. What part of "expression" in LT's add trace dialog did you
have trouble understanding?

AFAIA, the only options under 'add trace' are either for volta... oh
bollocks I'll have a better look before possibly digging myself into a
deeper hole...
Flippin' eck, Kev. You're right. I feature of the program I was
previously ignorant of. Thanks! ANd you didn't even mention SS once.
Most impressive.

I know...I still can't believe it either...I'm in shock...
