Based off previous stack overflow questions, I know what needs to be done is plt.yscale('log', nonposy = 'clip')or ax.set_yscale('log') However, this is resulting in a blank/empty plot. There was also a page that said this functionality does not exist- however, this was 6 years ago, and updates have happened since then.
fig, ax = plt.subplots()
ha = plt.subplot('111')
Pxx, freqs, bins, im = plt.specgram((tempdf[j]), NFFT=NFFT, noverlap = NOVERLAP, pad_to=PADTO, Fs=Fs)#, , mode='magnitude')
#plt.yscale('log')
#ax.set_yscale('log')
#plt.yscale('log', nonposy='clip')
plt.show()
