Thanks Sundaresh!

Yes, you are correct, that semicolon is unnecessary. I forgot to remove it. I created my original plot in Jupyter Lab prior to bringing the code to the PYTHON procedure. In Jupyter Lab if you add a semicolon after the last plotting statement, it removes unnecessary text above the plot. That semicolon does not do anything outside Jupyter or cause any issues. I will remove it to clean up the code. Thanks!
