    I've been using Qt charts to plot the frequency response data for an audio signal. I cant figure out how to use the Qt framework to create an audio Spectrogram (like these: https://www.google.nl/search?q=audio+spectrogram&safe=off&espv=2&biw=1280&bih=934&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjCj_fl3tXQAhVILcAKHbWfD0MQ_AUIBigB). Is this possible, and if so, how to do it ?

    Thanks in advance.

      Hi,
      if you know how to prepare and arrange your data for this kind of visualization, then yes: I would use Qt charts to display 2D-data and Qt Data Visualiazation for 3D-data (e.g. http://doc.qt.io/qt-5/qtdatavisualization-qmloscilloscope-example.html).
