Program crash when attempting to plot power spectrum

[pyjamashark]

When I try use one the plot option (ie if I right click on a trace) in in order to plot the power spectrum (FFT) the program crashes and I get the following error.

python start.py

I tried the development version and got a similar error:

Hi,

Sorry, those plot options are available by default from the underlying libraries, I didn't actually implement those options. Thanks for raising I will debug them.

In the mean time you could hit the show fft checkbox option and then plot that? I think the export -> SVG is probably the best way to save the plots.

Great, thanks for your help that works well!
