I am plotting three plots per audio file using subplots. How to made axis invisible?

audio
1 
path=glob.glob('............./*.wav') 

fig, ax =  plt.subplots(nrows=4, ncols=3, sharex=True)

    
for i in range(4) :
   
    y, sr = librosa.load(path[i], sr=16000)
    plt.axis('off')
    
    librosa.display.waveplot(y, sr, ax=ax[i, 0])  # put wave in row i, column 0
    
    
   
    mfcc=librosa.feature.mfcc(y) 
    plt.axis('off')
    librosa.display.specshow(mfcc, x_axis='time', ax=ax[i, 1]) # mfcc in row i, column 1
    

    S = librosa.feature.melspectrogram(y, sr)
    plt.axis('off')
    librosa.display.specshow(librosa.power_to_db(S), x_axis='time', y_axis='log', ax=ax[i, 2])  # spectrogram in row i, column 2

I tried different positions for plt.axis(off) But none is working only on the last plot it’s working. any suggestions @ptrblck sir plz help, I know this is out of forum discussion but if you can guide me,
Regards

Just to close the conversation and help others , I got the answer . After defining subplot axis off is used like this:

fig, ax =  plt.subplots(nrows=4, ncols=3, sharex=True)
[axi.set_axis_off() for axi in ax.ravel()]

and problem is solved :slight_smile:
