 This library uses Matplotlib as backend, and you can change all settings of [rcParams](https://matplotlib.org/stable/users/explain/customizing.html#matplotlibrc-sample) as you wish. Example: Using an already installed LaTeX installation for high-quality rendering of LaTeX labels and other text:
 
 #### More beautiful LaTeX
-```
+```julia
 rcParams = plt.PyDict(plt.matplotlib."rcParams")
 rcParams["text.usetex"] = true
 ```
 Just add this at the beginning or your script. You can change fonts, font sizes, colors etc.
 
 #### More beautiful GUI
 If you add the following line to your `.bashrc` file or to the script you use to start Julia:
-```
+```bash
 export MPLBACKEND=qt5agg
 ```
 you get a more beautiful GUI. This does not work on every PC, therefore it is not the default.
