  • Did you update conda? If so, does this answer your question? [After conda update, python kernel crashes when matplotlib is used](https://stackoverflow.com/q/69786885/7758804) – Trenton McKinney Nov 01 '21 at 11:48

    Also if you're plotting from a file, it needs `plt.show()` after `df[['datetime', 'adj']].plot(kind = 'line', figsize=[20,5])`. – Trenton McKinney Nov 01 '21 at 11:52
  • Thankyou very much, After I installed anaconda, I successly plot the graph. (I failed whiling using pip) – 良心燈塔 Nov 03 '21 at 08:22

There's no need to use the print function. Just call

df[['datetime', 'adj']].plot(kind = 'line', figsize=[20,5])
