Program crash when attempting to plot power spectrum #79

Open pyjamashark opened 5 years ago

pyjamashark commented 5 years ago

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.

I tried the development version and got a similar error:

/opt/anaconda/lib/python3.7/site-packages/sklearn/ensemble/weight_boosting.py:29: DeprecationWarning: numpy.core.umath_tests is an internal NumPy module and should not be imported.

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!
