[Matplotlib-users] use \mathbb when usetex=True

[ceguo <hh...@gm...>]

Hi,

I found when usetex is set to be True, \mathbb cannot return blackboard bold
font. A minimum reproducing code of mine is:

import matplotlib.pyplot as plt
from matplotlib import rcParams

params = {
  'backend':'ps',
  'ps.usedistiller':'xpdf',
  'axes.labelsize':22,
  'text.fontsize':20,
  'legend.fontsize':20,
  'xtick.labelsize':20,
  'ytick.labelsize':20,
  'text.usetex':True,
  'latex.preamble':r'\usepackage{amsmath,amsfonts,amssymb}',
  'figure.figsize':[8,6],
  'font.family':'serif',
  'font.serif':'Times New Roman'
}
rcParams.update(params)

plt.plot([0,1],[0,1],'r-',lw=3,label=r"Using $\mathbb{D}^p$")

plt.legend()

plt.show()

I want to keep my rcParams settings as unchanged as possible.

Ning
