No, it's all or none. But with usetex=False you can use mathtext to
format your labels, and then only the stuff in $$ will get formatted
as math using the matplotlib fonts and math layout engine.

You should be able to do this with a custom formatter::
import matplotlib.ticker as ticker
fmtbld = ticker.FormatStrFormatter(r'$\textbf{%1.2f}$')
ax.xaxis.set_major_formatter(fmtbld)
You should also be able to use textbf in the title, xlabel and ylabel.
Of course, for this simple solution, you have to hard-code your
precision. To take advantage of all the logic in
ticker.ScalarFormatter, you could inherit from it and override some
key pieces. But it might be better if we provide some hooks for you.
Darren, in ScalarFormatter.set_format, we have code like::
if self._usetex:
self.format = '$%s$' % self.format
elif self._useMathText:
self.format = '$\mathdefault{%s}$' % self.format
We could consider exposing a font setting here. Something along the lines of
self.fontcommand = None
if self._usetex:
if self.fontcommand = None:
self.format = '$%s$' % self.format
else:
self.format = '$%s{%s}$' % (self.fontcommand, self.format)
Then the user could do::
formatter = ticker.ScalarFormatter()
formatter.fontcommand = r'\mathbf'
and something similar for mathtext.
