cv2.imshow not working when using with plt.show

I am working on opencv4 and python 3 with matplotlib version 3.2.0 .

cv2.imshow("Original",image)
#after few lines
plt.plot(hist)
plt.xlim([0, 256])
plt.show()
cv2.waitKey(0)

The image is not displayed but only the plt.show is displayed. The image is displayed after closing the graph. I want them to be showed together, is it possible? This is the first time I am using matplotlib and only installed python3-tk. Is there anything else I should do? Would be grateful for any help.

plt.show() waits when you close plot window. imshow waits for waitKey call to show window. Put waitKey(205) just after imshow, it should work.
