[Matplotlib-users] automatic list of r'$2$'...

[vincent.adrien at gmail.com]

Well, isn't
```
Lx = np.arange(xmin, xmax + 1)
Lrx = [r"${}$".format(val) for val in Lx]  # aka 'list comprehension'
```
producing what you are looking for?

PS: in the long term, another (more global) approach might be to 
leverage Matplotlib's formatting capabilities like the ones introduced here:
http://matplotlib.org/gallery/ticks_and_spines/tick-formatters.html
or
https://matplotlib.org/tutorials/text/usetex.html
and then simply define the ticks (meaning their value) that you want.
