      Description

      I see a problem within the visualizer.  I think the axis scaling are incorrect. I attached 2 screens.

      The FFT shows a peak at 4e-2 ( = 40 Hz, correct ?)  
      The timeseries however suggest oscillation around 7-8 Hz. 
      These screenshots are from  www.thevirtualbrain.org/demo --> "Default project"
      at Operations page, see the latest simulation "2d_oscillator" and the latest FFT above it.
