Currently, there is no support for this. However, a monkey patching
can be a quick solution for now.
from matplotlib.text import Annotation
def draw(self, renderer):
x, y = self.xy
x, y = self._get_xy(x, y, self.xycoords)
if not self.axes.bbox.contains(x, y):
return
self.draw_real(renderer)
Annotation.draw_real = Annotation.draw
Annotation.draw = draw
ann = annotate("test", (0.5, 0.5), xytext=(0.6, 0.6),
arrowprops=dict(arrowstyle="->"))
I think this should be the default behavior (with optionally turned
off). If other developers don't object, i'll try to push this feature
into the svn.
