For some reason I cannot figure out how to draw a spectrogram together with a TextGrid. I can draw a waveform with a TextGrid, a pitch track with a TextGrid, just not the spectrogram. I can draw a spectrogram separately and a Textgrid separately, but they do not necessarily line up and it involves a lot of steps. Besides, my one tier TextGrid for some reason has an empty tier above it when I draw it separately. What am I missing?
