title: Change scale to logarithmic for Spectrum Analyzer in Simulink
body: <p>The title says it all. I have a graph showing in linear. I checked on Mathworks and it says you can only show in log (View >> Spectrum Settings >> Trace Options >> Scale) only if the spectrum doesn't contain negative values.</p>
  
  <p>So, I changed the span to start from Zero. But that didn't help as well.</p>
  
  <p><strong>How can I change the scale to log?</strong></p>
