  <p>Now I tried to plot the data with "quartals" on the x-axis and "counts" on the y-axis (with code below). It seems to be quiet simple but nothing works...</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import pandas as pd
  
  df = pd.read_csv('Mappe3.csv')
  df.plot(x="Quartals", y="Counts")
  plt.show()
