Hi:
I am having problems with the \dagger LaTex symbol. The following code
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.title(r'$ \dagger $')
plt.show()
produce a long Traceback that ends in
File "/usr/lib/pymodules/python2.6/matplotlib/mathtext.py", line 1997,
in raise_error
raise ParseFatalException(msg + "\n" + s)
ParseFatalException: Expected end of math '$'
$ \dagger $ (at char 0), (line:1, col:1)
Other LaTex symbols works OK. For instance, if I use plt.title(r'$
\diamond $') instead, it works. I checked in mathtext.py, and \dagger
is in the list of symbols.
I am running Matplotlib '0.99.1.1'.
Any idea about this problem?
Alejandro.
Indeed that is a bug. That is one of about a dozen missing symbols from the mapping that I just found be comparing the legacy Adobe Type1 name-to-Unicode mapping in matplotlib to the LaTeX-to-Unicode mapping that is currently used. I committed these to master here:
