AC Analysis - Log Amplitude Plot?

---------------------------------------------------------
AC analysis plots the amplitude of the signal at one or more
nominated circuit nodes against frequency, where the input
stimulus (a voltage source, say) has its frequency parameter
swept between limits set in the run dialogue box, and produces
the traditional frequency response graph.
It is even possible to "accumulate" plots, and the analysis
automatically re-runs if you change the circuit, so you get
instant feedback of the effect of, for example, changing a
component value in a filter network.
The analysis run can also be configured to perform multiple
sweeps with specific components being stepped through a series
of values.
What I have not managed to do though, is plot the Y axis
(voltage) on a log scale rather than linear, to get a dB scale.
Any ideas?
