title: How can you change the color and line type of an individual line in a line plot on Jupyter Notebook when plotting the entire Dataframe at once?
body: <p>I am trying to figure out how to change the line color and line type of an individual line after plotting an entire dataframe at once.</p>
  <p>This is a snapshot of my dataframe:
  <a href="https://i.stack.imgur.com/FdhNT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FdhNT.png" alt="dataframe" /></a></p>
  <p>Then I used this to plot it:</p>
  <pre><code>df_month.plot(figsize=(15,10), linewidth = 3.5)
  plt.xlabel('Months', fontsize=18)
  plt.ylabel('Average Precipitation (mm/d)', fontsize =19)
  plt.title('Precipitation near Cape Scott Wind Farm', fontsize=22)
  plt.savefig('CapeScott_precip.png')
  </code></pre>
  <p>And it resulted in this:</p>
  <p><a href="https://i.stack.imgur.com/1b0aR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1b0aR.png" alt="graph" /></a></p>
  <p>So I am wondering how I can change just the 'WRF-GFS' line to a dashed black line? Any guidance will be helpful, thank you!</p>
