Subscripting Text In Matplotlib Labels

this is my first question and I am a noob at python. So probably more to follow... I would like to create a figure with matplotlib. In the labels, I would like to include a chemica

Solution 1:

Try to change this line

plt.plot(x,y, label='H2O')

for this:

plt.plot(x,y, label='$H_2O$')

It shows with the font math.

Or also you can use the unicode character for that: ₂ (0xE2 / ₂)

plt.plot(x,y, label=u'H₂O')

or instead:

plt.plot(x,y, label=u"H\u2082O")

Please, note that unicode strings are noted as u"" instead than "".
