@rogerius1st well we have been there before 
There is no big Python installation involved just the Python extension of KNIME that will contain all the necessary packages.
The small Data App contains all the necessary settings to take care of the angles of the descriptions and the scale. So why not give it a try? You also get a .PNG file that you can then re-use. All descriptions are there to be configured in the data app …
You can adapt the color of the lines (the column used) and the format of the x-axis just by changing the settings in the Data App. Also you can control the grid (if you want it or not).
