 6. Read the SION files directly into Python and inspect the data there using the [Linktest Python Reader](Linktest-Python-Reader). This does not substitute a nice and easy to read report, but gives you the flexibility of looking at the data more in depth or to produce figures that better fit your needs.
 
+# The colourbar in the report extends outside its bounding box! How can I fix this?
+TLDR: Update MatPlotLib and Python.
+
+This bug is due to a MatPlotLib bug, which is first mentioned in issue [#6827](https://github.com/matplotlib/matplotlib/issues/6827). As we are relying on MatPlotLib for plotting we cannot fix this on our side. Once it has been patched out update Python and MatPlotLib.
+
+Alternatively, you can can increase the default rasterization resolution in PPI (Pixels Per Inch), which MatPlotLib for historic reasons calls DPI (Dots Per Inch, a quantity important for printing). To see how you can modify these variables globally checkout the [MatPlotLib Customization Guide](https://matplotlib.org/stable/tutorials/introductory/customizing.html). Often a value of 300 is enough. **WARNING!** This will increase you file size.

 # What do the weird unit prefixes, like ki, Mi and Gi, mean?
