Please see the piece of the code I am using to produce an image. At the end, I want to write a text withing the image. There, i want to use "~" symbol using TeX rendering set through rc parameters. But, when I run the code, it doesn't even print the "tilde" symbol. Any idea, how can I incorporate this? Thanks. 

from matplotlib import rc
rc('text', usetex=True)
rc('font',size=size_axislabels,**{'family':'serif','serif':['Times'],'weight' : 'bold'})
bbox_props = dict(boxstyle="Square,pad=0.3", fc="w", ec="0.5", lw=3)    
........
........
ax.text(90, 41, r"Distance: $~$ 500 pc", ha="center", va="center", size=20,transform=ax.get_transform('galactic'),
        bbox=bbox_props)

To post my comment as an answer:

The problem ist that you are not using the correct latex command for a tilde. In math mode, you can use $\sim$ to write a tilde.
