  • Welcome to SO! I embedded some of your post more neatly (don't worry, you can embed images with a little more reputation), but your traceback seems cut off! – ti7 Sep 04 '20 at 15:27
  • Does this answer your question? [Matplotlib: ValueError: x and y must have same first dimension](https://stackoverflow.com/questions/26690480/matplotlib-valueerror-x-and-y-must-have-same-first-dimension) – ti7 Sep 04 '20 at 15:28
  • Watch out; you have also posted your quandl API key and should change it! – ti7 Sep 04 '20 at 15:30
  • i think len(X) and len(y) has same value that why this code show this error but – abhishek sachan Sep 04 '20 at 19:57
