[Matplotlib-users] How do i store plot data as numpy ndarray..

[Carlton Banks]

Hi guys.. 

I seem to have a problems with converting my plot to a numpy ndarray - 
Such that if I made a imshow of the numpy ndarray i would see am image similar to the lmage i created.. 

librosa.display.specshow(static.T,sr=16000,x_axis='frames',y_axis='mel',hop_length=160,cmap=cm.jet)
plt.title("log mel power spectrum of " + name)
plt.colorbar(format='%+02.0f dB')
plt.tight_layout()
plt.savefig(plot+"/"+name+"_plot_static_conv.png")
plt.show()
This will show an image such as:



But if i try to store it as a numpy ndarray and then trying to plot it using this code
convert = plt.get_cmap(cm.jet)
numpy_output_static = convert(static.T)
plt.imshow(numpy_output_static)
plt.show()
raw_input("sadas")
I see something like this
