Plots are not appearing in Pycharm Follow

I am new to Pycharm. I did run below scripts in Jupyter and it did work fine. Why don't plots appear in the Pycharm console? Do these libraries only specific to Jupyter? What should I have to follow to get the scripts in Pycharm

Here is the Q I've posted in SO. Noone has replied yet.
