transfer function error plotting

I'm trying to write a transfer function of LRC filter but when i want to plot on XY graph i receive an error message.

Seems that the product between an inductance and resistance value is problematic.

Could you help me?

Many people here still have just Prime 3 installed as they did not bother upgrading tp version 3.1. They can't read your file es PTC had dicided that different version should not be interoperable. P3.0 can't read P3.1 files and P3.1 can't write P3.0 files. Unbelievable, but true.

So its always better to provide a screenshot or a pdf print of your file in addition to the worksheet itself.

Just got hold on an 3.1 installation.

The reason why your plot fails is because T(f) has unit Ohm but to be able to take the log of it, it has to be dimensionless.

The quality factor must be dimensionless, and the bandwidth must be in Hz or, but more rare, in radians / seconds as well.
