HVSR persistence of a signal with time

[riccardo]

In geopsy I can evaluate the directionality of a signal with H/V Rotate and Spectrum Rotate plots, to see if a signal is natural or not.

Is it possible to have a plot of the persistence of a signal with time.
a plot with "time" on Y and amplitude/frequency on X (or viceversa)?

Currently not, but it is an option we will certainly implement in a close future
