title: Plotting formula and data at the same time using python
body: <p>Is there anyway to plot formula and insert data points in the same graph using python?</p>
  <p>Plus, if those data points are to be from excel spreadsheet, does the python allows to import it?</p>
  <p>I would really appreciate if someone could explain it to me with codes if it is possible.</p>
  <p>Thanks,</p>
