power spectrum

[Arne Biastoch <abiastoch@xxxxxxxxxxxxxxx>]

Hi Ferreters!

I have created a power spectrum of a time series (with gmt_power.jnl). 
Two questions:

1. Is it possible to plot the frequency axis as a logarithmic scale?

2. Is it possible to plot the values over period instead over frequency
   (1/T --> T)?

Thanks.

Ciao,
	Arne
