title: Chart visualization, one year with multiple visualization points
body: <p>I am trying to code a very simple visualization - election_year and number of votes on a chart.
  However, last 3 times the elections were held the same year - in April, July and November of 2021, which the charts reads as one event. How can I break the year into parts to create several chart points?
  Here's the code:</p>
  <pre><code>import matplotlib.pyplot as plt
  election_year = [2009, 2013, 2014, 2017, 2021, 2021, 2021]
  voters = [1678641, 1081605, 1072491, 1147283, 837671, 642165, 596456]
  plt.plot(election_year, voters)
  plt.show()
  </code></pre>
