What is the character or chain of characters in the code of matplotlib text field to break the line so as to avoid having too long code lines?
for example:
plt.text(0.5, 0.5,
r'$\mathsf{sin\left(\frac{\pi}{180} f_1 \theta + \varphi_1\right) + B sin\left(\frac{\pi}{180} f_2 \theta + \varphi_2\right)}$'
using "\" to break the long line yields in printing in unformatted text.
I usually take advantage of string literal concatenation. IOW, if you have strings right next to each other without any intervening operator then they're automatically joined:
>>> "a" + "b"
'ab'
>>> "a" "b"
'ab'
and so
plt.text(0.5, 0.5,
r'$\mathsf{sin\left(\frac{\pi}{180} f_1 \theta + \varphi_1\right)'
r' + B sin\left(\frac{\pi}{180} f_2 \theta + \varphi_2\right)}$')
works too. (Since this is TeX I added some extra spaces to bring the two lines into alignment; if we were working with something which was more white-space sensitive that wouldn't work.)
