I feel that a main advantage of matplotlib (over other solutions I have
used) is that there is a complete programming language available. In
this case, just use the standard string handling of python.
See e.g. http://docs.python.org/library/stdtypes.html#string-formatting
Untested code:
annotation_string = "f(x) = %f * x + %f R^2 = %f" % (gradient,
intercept, r-value)
ax.annotate(annotation_string,
xy=(2.9,-0.75), xytext=(2.9,-0.75))
