-        There is a problem with the Tkinter and matplotlib version causing the backend not to work for GUI so you cannot do graphics except saving it to a file and opening it afterwards (with ``eog`` for instance, if you have logged in with ``-X`` or ``-Y``). You can use this script to save it to a file:
-
-      .. code-block:: python
-
-         import pandas as pd
-         import matplotlib
-         import matplotlib.pyplot as plt
-         matplotlib.use('Agg')
-         dataframe = pd.read_csv("scottish_hills.csv")
-         x = dataframe.Height
-         y = dataframe.Latitude
-         plt.scatter(x, y)
-         plt.savefig("myplot.png")
-

    **CHALLENGE: How would you do it so you could run as a batch script?**
 
    - Hint: The main difference is that here we cannot open the plot directly, but have to save to a file instead, for instance with ``plt.savefig("myplot.png")``.
